Southwest Credit Systems, L.P. Debt Collection Complaint

Southwest Credit Systems, L.P. Debt collection department,

Other (phone, health club, etc.) Cont'd attempts collect debt not owed Debt is not mine Alabama

I got cable TV through -, and about a month later I decided to move and I called - to see about moving my service and they ask for the address I was moving to, they ran the new address and told me that they do not service that address. I told them that I had to move and I would just have to cancel my cable and internet. I paid for the time I had and used the service up until I moved. I sent the equipment back and I still received a bill for $350.00. I called - and explained to them I had called and canceled the service and they tried to tell me that I did not cancel that it went two months past due then they disconnected the service due to non payment. This is not true nor accurate. And I do not owe them - I called in to cancel this service and it should have been disconnected immediately because I was no longer even living at that address and the boxes were already packed up. You can even see from the Internet usage for the time they are trying to charge me for was - because it was not even connected. I feel as if I am not responsible for this debt. I refuse to pay it, I pay all my bills on time but I 'm not going to pay for someone else 's mistake. Please help me resolve this issue because I tried to handle it on my own and got no where.
