Internet Comcast Xfinity

Comcast Xfinity, I just want the name to be correct and foremost before I start this complaint. Let me start with I already knew this company had a bad rep, but I went with them anyways because Ive always gotten the Xfinity prepaid box. It used to be easy to call and add money for 30 days of unlimited Internet. Let me also start by saying I've had Xfinity prepaid box for a year, one day the box just stopped working. I was confused and went online and the Xfinity app to find out how to fix this. It's started with about 3 foreign representatives  to understand I was just stating my box wasn't working and I didn't understand how it just stopped. They finally agreed after hours of me unplugging and turning off and on the box to have a tech come out. The tech came out that following Monday. Saturday was when the box stopped working.  That Monday I tech came out. He literally came in and tested the box and told us we simply needed a new box, that we would simply just need to return our box and we should receive a new one with added days for our missed service. That the internet prepaid boxes sometimes don't last very long. That Tuesday I got up and called my boost mobile store that I bought the box from, they told me they no longer carried the prepaid boxes. So I called another boost mobile store in the area. They told me they did and just to come in with the receipt. I explain to the store that I did buy the box over a year ago. But he assured me this is fine as long as I have the receipt. So came to boost mobile with my old box, and when I came to the front of the line the cashier told me he would not be able to exchange the box because its been purchased over a year ago, which I totally understood, that I might have to purchase a new one. So we agreed to purchase a new box for $66 I believe that came with 30 days of prepaid Internet. He told me he would have resign me up to start the new box. Like a whole new account. I said that's fine but can I please have my missed days back, he said yes it should be on there. I gave him my information to send up for my new account. I went home content thinking the box would work just like it did whenever I first contracted with Xfinity. I came home, and guess what? The box did not work. So I went back to the phone. At this point I was thrown around through representatives. I honestly believe they did not speak English  . Eventually I was in a rush to get my daughter from daycare, I was on the phone with rep, honestly just saying all I want is my internet and what I paid for at this point. The rep agreed told me I just had to sign off on a few things through text message. So I rushed through and signed off. Telling him I did not want to put my card info online when I am prepaid. He said I wouldn't. Long story short I ended up with 280 bill from Xfinity. The charge the tech for coming out and putting "wires installation" in my apartment when that did not happen. Also I was paying for internet daily. Within 10 days I was at 280 bill. Finally I called cancelled and took the box back to boost mobile. Told them I'm fed up. And they told me whomever sold me the box never hooked it up correctly, and then also Xfinity had no idea what I was talking about. He fixed my box and I never looked back. But got stuck with that bill of $280. I've been able to dispute the charges and got it down to $23. But the point is the point. Xfinity customer service does not understand anything. I coulda screamed it till I turned blue. And they still would just sign me up for internet. I know boost mobile is not no angel for this as well. But I'm way more frustrated with Xfinity Comcast for charging me and literally did exactly what I asked them not to do. At the end of all this I talked to about 18 representatives that still could not figure it out.
