Totalsports is total nonsense

I had a totalsports account that fell behind on payments. I have been trying for six months to try and settle the bill and totalsports themselves dont even know who they sold my account to or how much i even owe them. I am baffled as to how in 2021 that is even possible. I want to pay you but none of your branches or head office knows whats going on. how the hell will I.
