Someone at this number left a few automated vm saying to call back to avoid repercussions. I called back, They told me the last XXXX of the ssn they had on file stating they are collecting for a loan - think a payday loan, however .... they can not or will not tell me who the original lender supposedly was. Said I owe {$550.00}. I can offer them a settlement. They have my cell phone # and last XXXX of my ss # and said they know I have a bank account at a credit union. I have asked them if I find that it IS a valid loan and I pay this - - how do I know they wo n't come back with another XXXX. He said he ca n't guarantee that since they do n't know the lender? How can they collect on an unspecified loan? I cleared up the few nightmare payday loans I had taken out in XXXX 
Thank youCaller is " XXXX '' @ XXXX
