Mrp mobile treats customers badly

Doing business with mrp mobile is rather sad and totally disappointing. They stopped debiting my account and I kept trying to enquire the reason for this. I later requested banking details from them which I eventually received with a final notice with an over due amount and an outstanding amount which was equivalent to 10 payments which I made every month thereafter. They now claim I owe them another 5 payments. Also they continuously debit my account after I told them I will make an eft payment monthly. Now I have been handed over to lawyers where they are claiming more money from me. This is ridiculous and I have tried so many times to get them to remedy this problem. With no joy till this date. Thank you Mrs N Husain
