In January of 2013 I had a bill that needed to be paid and I thought I had taken care of it. I hadn't received any more notices after giving them full payment so I went on with my life. Now it is February of 2015 and I just received a notice in the mail from a collection agency saying that I had never paid this debt. WHAT!!! I was so infuriated when I called this company because I DID pay this debt. The lady told me that they had sent the debt to them in October of last year. I am in the process of sending them a request for debt validation and also a dispute for this debt. My question is, what are the legal time frames of both the hospital and the collection agency? I just don't feel like any of this is right. 1. The debt was paid when I got the bill. 2. They waited almost 2 years to send it to collections. and 3. It was sent to this agency in October and I never received a phone call or a letter stating I was in collections until February. Any and all help is much appreciated. I just want to know if anything illegal happened while I'm in the process of disputing this debt.
