Fake Promotion, Xfinity Support is the worst.

This is the entire story of everything with this problem, from the very beginning. I moved to a new place 08/16. Originally, I was only going to pay for my home internet, but when I was trying to set up my connection with my own personal modem/router, I ran into many issues. After 5 hours on chat the first day, i was told to get the Xfinity modem/router from the local store instead. So on 08/17, I got the modem/router from Xfinity and still experienced the same issue. I reached out to support via chat again, and while we did some troubleshooting, the representative offered me a "promotion" for the inconvenience. It came with a "free iPad" and I was told I would pay the same amount overall. I agreed, because it sounded like a good deal. They stated that they would send a technician to my new house on 08/18, and the internet started working properly. 

I received my first bill, and it was the full amount for internet and mobile. I contacted customer service from 09/21-09/24, and I was bounced around to over 10 people for 3 days and no one gave me an answer. A handful of them told me that the promotion I was promised is only for smartphones, but I was told I would get an iPad. I asked for a supervisor, and they did not get me connected to one. One person said that the only solution would be for me to contact them every month in order for them to MANUALLY update the bill to the proper amount, which is absurd. With how the customer service has been, that would mean I need to spend 3+ hours a month just to get what I was promised. I finally got someone who gave me an "answer" on 09/24. I was told that my internet bill would be discounted $40, and then I would be charged for the mobile bill of $29 and some change. The first month (August to September) would be charged the full amount, but September to October's bill would have the discounted price. My bill came and it was full priced at $80 as well as $55 for the mobile service, and I was charged on 10/11. I contacted support that same day, and they stated that they would give me a refund. And as of today (10/17), I have yet to be refunded. I contacted support via chat, I asked for a supervisor, and I was speaking to one, but they transferred me to someone else, who also claimed to be a supervisor, who also transferred me to another team. Then another representative told me there are no supervisors for their chat. 

At this point, I have spent over 24 hours total discussing this with Xfinity representatives. I have been told many things, and most of which either being lies or just a blanket statement saying it will be taken care of, when it never is handled. 

So here is what I need:
1. I was promised my internet bill would be discounted to $40. I need that to be permanent until I am no longer with Xfinity. I am not going to spend my time to have Xfinity "manually" update this bill. 
2. I was charged $80 on two months that should have been $40, I need to be refunded. NOT CREDITED. Refunded. 
3. I need to talk to someone who is a higher up. I have asked to speak to a supervisor or a manager. Each time I have gotten in contact with a "supervisor", they have transferred me to someone else. That is not a supervisor. I need to speak to someone that can actually solve my problem, not transfer me from one team to another. 

4. I need proper clarification of the issue I am going through, as well as a documented resolution. I have transcripts of a handful of chats I have had. However, I need records of all the phone calls I made with Xfinity as well as a cohesive email with all the chat logs starting from 08/17.
5. I would like to be compensated. I have had to take time away from work, which I was not paid for. I had to spend HOURS talking to people who would just transfer me to a different team, which would just lead to them transferring me back to the team I was talking to. I was also promised a promotion that ended up being false. Which is horrifically poor customer service. 

This ordeal has been going on for 2 months, and I guarantee you it will not be over anytime soon. I was promised a promotion, was lied about the terms, then was told I would be given the promotion, and then was told that it is all my fault and I am the idiot. The chat rep told me I would be getting a call from a supervisor. And honestly, I don't think I will be getting that call. But we will see. Whoever from Xfinity is reading this, do not contact me unless you are a supervisor or a higher-level associate who can get this FIXED for me.
