Herbert P. Sears Co., Inc. Debt collection department,

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

I started receiving bills sometime in - or - from - - from out of no where. I know I do n't owe them anything because I just paid off my - contract and I had n't gone to see the - in over a year and every time I went in to see them I had to sign a contract for services and pay before they started any sort of treatment on me. I had a - balance on my account. I contacted the office talked to - who was going to look into it for me because she showed a - balance on my account on - and on -. Did n't hear anything back. I still kept receiving bills. I contacted the office left messages for the manager to call me back, never received any calls. I called the - number left messages to send me a detailed explanation of what I was being billed for, date of service, copy of contract I signed on this date of service, and what my insurance paid for. I just kept receiving invoices requesting money and they added on late fees. I sent the company a letter requesting everything I asked for on my voice message and instead was sent to collection. At this point I 'm really upset and I do n't know what to do. I 'm still receiving bills for the late fees from - but they already sent the bill with the late fees included to collection?? Is this even legal?
