MCA Legal Group Of America NLA Legal Group Took money out of my account and never even contacted my lender Irvine, California

MCA Legal Group of America who use to go by NLA law firm and RMA law firm sent out a letter to my parents in New Mexico which looked like it came from Bank of America- they are old so they ended up giving them money to have their loan payment reduced through the HAMP program ( which is free) well after three hundred dollars and five months nothing has been done. The bank says they do not even know who these people are? I have been told that because they used ACH for their payments, it is possible for the bank to reverse the charges... I just don't want this to happen to anyone else!I have spoken to the AG and they have had many of the same complaints and said they work with California closely and will be shutting this company down.
