My phone was stolen by fraud

Same story as many others. My phone arrived, I got a call that I needed to return it - it was refurbished- I returned it.  I talked to legitimate Xfinity employees and told them this and no one said anything about fraud until 11 days after I returned phone.  I filed a police report.  I worked with your fraud division.  I was told this is my fault for falling for the scam and I still owe the money.  I called tonight to discuss getting a final billing as I dont believe in working with a business who would treat customers this way.  You leaked the information after all - I was told by a manager I might as well go after Apple, that this isn't Xfinitys fault/. I agree that it isn't but in the business I am in we support our customers even when it costs because it what's you do.  Xfinity basically told me to get lost.  Ok fine.  I will make sure to file a complaint with the BBB, and spread the word on social media to avoid your scammy mobile service.  Shame on you.
