<prompt> Human: So my parents have a 30 year mortgage with 140,000 left on it from Bank of America. This month, out of the blue, we get bills from GreenTree Servicing saying that we owe them our mortgage payment. We payed the June bill, but they wont update the fact that we payed so now we cant even pay our july bill w. out also paying the june bill, again.Does anyone know if this is a malicious company and if we should be taking steps to defend ourselves? Ive read complaints online that they have received many cheap mortgages from BoA and are taking peoples homes from them.  <response>: Get confirmation from BofA that this transfer is legit. You get no credit if you pay your mortgage to the wrong party.
