I had Comcast a couple years ago and canceled when I was out of contract and the bill had ballooned to nearly $200 a month. I returned the equipment to my local Xfinity store and that was that. Fast forward a bit later and I find out I supposedly owe them for equipment that wasn't returned and past due bills. I tried disputing it through Credit Karma but that was to no avail. Just today I got something in the mail from a debt collector saying I could pay the full amount or 65% of it and be free of it. It's really hurting my credit so I was wondering if there was anything I could do other than paying for equipment I returned to them?
