<prompt> Human: I live with one roommate and weve been paying roughly 140 per month for combined cable and Internet. Historically, weve used 400-500Gb per month. Our cap is 1Tb.I transferred the service in the last week of May to a new location, and Comcast claims that in the last 5 days of the month at the new location, I used 3.5Tb of data, and have charged me 700 on top of the bill.I called to dispute it, and the agents response was, people are capable of anything. To me, this is the most laughable response. He also told me they do not track how the data is used, so Im not able to receive a bill on the breakdown of usage.My belief is that there was some system error when they migrated my service to my new location. Comcast refused to entertain this notion when I spoke with them.Ill address some possible commentsconcerns:1 Yes, we both stream content fairly regularly and always have. That was factored into the 500Gb max we have hit before.2 No, neither of us torrent or use file sharing services.3 We use a Comcast issued modem that is password protected, and we cant change it.4 There has been no drop in internet speeds at all, and it has been very consistent at performing where it should be. This leads me to believe there has been no mass usage that would lead to the 3.5Tb.Im mostly just frustrated and angry, and I dont know how to dispute this and have it corrected. Both my roommate and I are young and already do not make enough for us to shrug this off. Any help at all is appreciated.Edit: I was transferred once to the supervisor level and he refused to transfer me further after multiple requests to do so. Also, speed is 75mb. Its that X1 package or whatever.  <response>: You need to call and talk to someone who knows what theyre doing. I believe option 4 is Customer Retention - they are usually much more skilled.Escalate it. Also, report that the last person you spoke to laughed at you and refused to be helpful. Comcast is seriously trying to turn around their customer service.This is worth leaving them over. Explain that you are being charged to bogus things, and historically use a tenth of what theyre charging you for. Print out all your previous bills and explain that youre ready to go to arbitration. These supervisors are humans and work really, really hard to help you.
