About Foundever
Sitel Group was a major global customer experience, contact center, outsourcing, and business process services company. The organization provided customer care, technical support, sales, back-office services, collections, and other outsourced customer experience services for large companies across industries such as banking, healthcare, insurance, retail, technology, telecommunications, travel, and utilities.
The company underwent a major transformation after combining Sitel Group and SYKES. On March 1, 2023, Sitel Group officially rebranded as Foundever. The Foundever name now represents the combined global business, so references to Sitel Group as the current operating brand are outdated. Foundever describes itself as a global customer experience company serving more than 800 brands across more than 45 countries.
Foundever’s current global headquarters is in Luxembourg, while its principal U.S. operating entity uses a corporate address in Miami, Florida. Current official Foundever materials identify Foundever Operating Corporation, 600 Brickell Avenue, Suite 3200, Miami, Florida 33131-3089 as a U.S. corporate address.

How to File a Complaint Against Sitel / Foundever
Customers, employees, applicants, vendors, or business partners who have a complaint involving Foundever should first determine whether the issue relates directly to Foundever or to a client company for which Foundever provides outsourced customer support. This distinction is important because many people interact with Foundever employees while contacting another brand’s customer service department. Gather all relevant emails, call records, case numbers, screenshots, job information, names, dates, and documentation before beginning the complaint process.
Step 1: Contact the Relevant Customer Service Program or Foundever Office
If your complaint arose while dealing with customer service for another brand, begin with the official complaint or escalation process of that brand. Foundever may provide the agents and technology, but the client company usually controls the customer account, policies, refunds, products, and final service decisions. If the complaint concerns Foundever directly, such as employment, recruiting, privacy, or corporate operations, use the relevant Foundever contact channel. Explain the issue clearly, provide important dates and reference information, and request that the concern be documented. Keep records of the response and any case or ticket number provided.
Step 2: Request Escalation to a Supervisor or Appropriate Department
If the initial contact does not resolve the matter, ask for review by a supervisor, manager, recruiting representative, privacy team, or appropriate corporate department. Explain what steps have already been taken and identify exactly what remains unresolved. Provide supporting documents where appropriate and keep your explanation consistent so the company can follow the history of the complaint. Ask what further investigation or review will take place and whether a written response will be provided. Maintain copies of emails, messages, case numbers, and other relevant records.
Step 3: Submit a Written Complaint to Foundever
For a direct Foundever issue, written communication can provide a clearer record than telephone conversations alone. Describe the complaint in chronological order and include your name, contact information, relevant Foundever location, dates, case numbers, and the outcome you are requesting. Privacy-related concerns can be sent to privacy@foundever.com, while media questions should go to media@foundever.com. Employment applicants should use the careers system and the recruiting contacts associated with their application. Keep copies of every written submission and response.
Step 4: Escalate the Complaint to the U.S. Corporate Office
For a serious U.S. corporate matter that remains unresolved, written correspondence may be directed to Foundever Operating Corporation, 600 Brickell Avenue, Suite 3200, Miami, FL 33131-3089, United States. Include your full contact information, relevant office or account information, previous case details, important dates, and a clear explanation of the complaint. State the resolution you are requesting and include copies rather than originals of supporting documents. Avoid sending passwords, full payment-card numbers, or unnecessary confidential information. Keep proof of delivery and a full copy of the complaint.
Step 5: Use an Appropriate External Complaint Process if Necessary
If a serious issue remains unresolved, the appropriate external process depends on the nature of the complaint. Employment disputes may involve a labor or employment agency, privacy concerns may fall under a privacy regulator, and consumer disputes involving one of Foundever’s client brands may need to be filed against that client company rather than Foundever. Applicants who believe they encountered recruitment fraud should preserve messages, phone numbers, emails, and payment requests before reporting the incident. Organize all documentation before escalating externally so the reviewing organization can clearly understand the issue and the steps already taken.
