PRESCRIBED DEBT 15 YEARS OLD

They are trying me to pay for a loan that was taken out 15years ago. they think we all stupid.. I have now lodged a complaint with the Debt cOLLECTORS COUNCIL. I have warned them on numerous occasions not to contact me for prescribed debt of 15 years old.. They want me to forward prescription proof.. DUMB ASSES, PRESCRIPTION IS AUTOMATIC.. ive requested numerous times to 4 different agents, proof of the account they collecting on, which should show the date the account was opened.. Guess What!!! Then they stop, 2 days later, they let a totally new agent, try their luck with me again, my story doesn't change, my tactic doesnt change.. will see you in court for the harassment charges
