Installment loan Problems when you are unable to pay California

I got a loan from Key Bank for a pool in -. I ended up short selling the house in -, and stopped paying the loan. The loan was sent to collectors and I arranged automatic payments with them in -. I noticed after about a year that the amount owed was n't going down, so I called and spoke to the collection agency and they told me that Key Bank was still charging interest, as they did not and could not charge interest. I called Key bank and they had no idea how that happened. The interest charges stopped after that. In -, my automatic payment stopped, so I called the collectors and asked why, and they told me Key bank took the debt back. I called Key bank and was told the want the entire amount owed, not the little payments I was making, so I said send me a bill. The bill never came, and I got a call from - - on -/-/- at -, and he had no records of my previous contact with Key bank. I requested my proof of payments from him, and I gave him my address, and I 'm still waiting. Key bank has my address and phone number, but they keep calling my mother and harassing her. I need proof of payments from them to show that they were charging interest on a debt they had transferred to collectors, please help, thank you.
