When a bill collector tells you they are trying to collect a debt for someone dont they have to prove that they have a contract with that someone and show you the legal agreement they have with that someone.How do i know gs collection has the right to bug me about a bill i have with lets say chase visa?Just because some bill collector tells me they aquired my account does not mean its true.Validation of a debt does not mean that the bill collector can tell you that you now owe them the money and you must now deal with them without some sort of legal proof they have that legal right.Yes its true sir i do owe chase visa 500.00 but i dont owe gs collection service a dime.Imagine if somebody called you and said you know that 500.00 dollors you owe uncle ralf well pay me instead or i will sue you.Your uncle ralf said it was ok.Show me the proof!!!!!!!!
