Paying for a phone that I returned

I’ve been dealing with the same issue for weeks now. I returned my old devices, but Xfinity keeps charging me $668 for them. I’ve spoken with multiple agents, been promised credits, escalations, callbacks, and even had a supervisor confirm I shouldn’t owe this — yet the charge is still there.

On top of that:

• Their chat system loops endlessly and makes it nearly impossible to reach a real person.
• I’ve been told conflicting things about deferrals and repayment plans.
• Agents admit they “don’t have access” to remove charges, even though I followed all return instructions correctly.
• I was even warned my service could be shut off over these unfair charges.

This has been exhausting. I’ve paid what I actually owe, and I’ve done everything right, yet I’m still being threatened with service suspension over their billing errors.

⚠️ Customers deserve better. Has anyone else gone through this same mess with Xfinity Mobile returns and billing? How did you finally get it resolved?
