I paid a bill on time in 2005 and AMO recoveries started calling me over a year later, in Jan. 2007, saying I hadn't paid. I sent proof from my bank statement, but they weren't satisfied. I had to call or fax different people over 30 times to create a paper trail proving that I had paid my bill. At one point they lied to me on the phone saying I had paid in Dec. 06, so I sent them a fax proving otherwise, and they never apologized, just came up with new reasons not to fix my credit score.
Finally one of their reps admitted that I had indeed paid them in 05. They said they would fix my credit report and mail me proof. Instead, they did nothing, and a month later started calling me again telling me to pay them.
The amount I paid them is 725 dollars, and they keep trying to extort double my money from me. Just today they lied again and said that the website I paid my bill on would only credit the hospital directly, not them. I called the website and they confirmed the opposite, they only pay AMO, which is supposed to pay the hospital themselves.
So I gave AMO money in 05 which they kept but did not pay the hospital apparently. This is the worst company of any kind I have ever experienced. I have no idea how any of them sleep at night.
