Comcast / Xfinity review: Xfinity mobile

I purchased through my Xfinity account a Samsung X Flip5 for my birthday on August 7th of this year and have had nothing but problems with it since I received it. While I was speaking with an agent who was leading me step by step in the activation process of the phone the bottom portion of the screen kept flickering off and on. I mentioned this to the agent and when we finished with transfer/activation the bottom of the screen was working but less than 24 hours the screen went black and stayed that way. After speaking with at least 6 agents over a weeks time I finally spoke with someone that understood what I was saying. He sent me another phone and emailed a label to me to send the broken phone back within 20 days...I took the phone to FedEx within a week of receiving the replacement phone...End of situation? Nope. It has gotten worse. The phone that I sent back to Xfinity was sent back to me and I received an email telling me it was damaged. Well, what is going on at Xfinity in the Phillippines that this is happening. I feel like I'm in a nightmare. I received numerous messages by way of texts or emails that my service was going to be interrupted for an outstanding balance of over $1000. I spoke with an agent in the Phillippines who told me that his records showed I had a balance of $45. I paid $50 and two days later I got another disconnect notice for $70 and I paid that. I got another notice of disconnect and spoke with another agent in the Phillippines again this morning, Sept. 12th who told me that he and his supervisor had fixed everything and that there was a lack of communication between offices and that's why this happened and I will have to send the damaged phone back and that FedEx would be contacting me for a pick up time. Well guess what happened while I was on a call with a family member the call dropped. My service has been disconnected and I had to speak with yet another person in the Phillippines who told me that my service would be restored in 2-4 hours. When this mess is finally sorted out, I will be sending the phone that is currently working back to Xfinity and I will use another carrier. Your agents keep reminding me that I'm a Gold customer but the treatment I've been getting makes me feel like a brown customer...get it? I'm very disappointed with Xfinity...especially when there is no one in the US that your customers can speak with without having to push buttons for 10-15 minutes just to get an agent in another country.
