Unhappy with service

I have requested prescription on my account a year ago and every time my account just gets handed over to a different debt collector. This debt is older than 5 years and I have been requested numerous times prescription on this account. The debt agencies keep giving me false info and lying to me. I am fed up with this. I will take the matter to the Ombudsman. I am being treated unfairly and keep getting the run around with this account. I want a response from Old Mutual. There are laws in S. A. that assist consumers in these cases but the companies don't adhere and get away with it. Fed with Old mutual!!!!!!!
