Xfinity Mobile Device credits and customer service

I've been dealing with an issue since I've got my phones back at the end of June. Today is November 3rd and I'm still dealing with this issue. It's been a nightmare over 60 hours on the phone. Numerous chats getting hung up on numerous times. No callbacks after being on the line for hours. It's just ridiculous. Customer service is terrible. They don't care. You get ticket number after ticket number after ticket number and nothing gets handled. Every time you call they ask the same questions. You try to give you them a ticket number. They don't want it till you have to force it on them. Then they start listening but nothing happens. They canceled my lines on their own and reopened them, canceled them and then reopen them. So I'm not going to get the device credits I was promised even though I didn't request to cancel them. I don't know what's going on with you Xfinity but you're cheating me out of $1,000 and I'm getting ready to terminate my service with you guys home and phones. This is ridiculous. This needs to be handled correctly by someone local and not selling over the phone or chatting. I need to talk to somebody that speaks good English. Sorry not sorry
