Comcast cheats people out of refunds

I moved into a house in July 2023 and set up account with them. Then a couple weeks later they disconnected my service. At first I thought it had something to do with my bill but apparently after days of talking to customer service apparently there was another account that had nothing to do with me attached to the house prior to me moving in. Of course Comcast didn't mentioned any of this on the phone when they set up & charged me for the account they set up for me. So for almost 3 weeks I dealt with customer service giving me the runaround whether it was on the phone or at a physical location. Kept talking about this past account on the house that has nothing to do with me! Not in my name or anything. Then when I submitted a copy of my lease & my electric bill to prove that I had just moved in the house they basically didn't except thise even though they told me that's what I needed. So I got tired of dealing with there [Edited: "Language"] and decided I was just going to return the equipment which was within 30 days of when they started my account for a promised refund for (All) the charges even installation incurred for a account that was set for me that apparently wasn't actually suppose to be set up for me because of these old account by a previous renter. Was told by every customer representative on the phone and at physical location I would receive a refund specifically a $100 charge for installation. But after 6 weeks of waiting for my refund with no avail I called and Comcast has the nerve to tell me that they cannot give me a refund for the charges even though I within the thirty days that's clearly within their policy. The reasoning being that the installation service had been done. Yeah on a account that they were never suppose to set up in the first place according to them because of this other account that had nothing to do with that had gone into collections. So to make a long story. I believe Comcast doesn't want to issue me my refund for my account charges because they indirectly want to hold me responsible for this past account on the house I moved into that had nothing to do with even when I proved it to them with my lease, electric bill, and electric bill greeting letter. They are vindictive to there new customers based on other non responsible customers behavior. I wouldn't recommend every dealing Comcast if you're looking to getting treated fairly or with the truth. They punish there customer when they Comcast is the one who makes the mistake. They're just concerned about opening new accounts regardless of circumstances because they can take the customer money @and shut your account off arbitrarily whenever they want even if you can prove them wrong! Comcast/ Xfinity  is the worst company I've every dealt with and I wouldn't recommend dealing with them for any services! There corporate thiefs!
