No responce on any queries

I upgraded my contracts in March 2015 on two of my numbers that was on topup. It seems that the limit was never set agian. I started getting huge bills from mtn and have sent hundreds of emails and logged numerous queries with the call centres with reference numbers for each query. This problem as been dragging for seven months now and it is impossible to get hold of the MTN legal department or the credit controlers. everytime i called 808 to get transfered to legal they said that legal does not accept calls anymore. A few consultants gave me numbers to contact them directly but the numbers Never work. my account was made open without my agreement and I am being held liable for charges that I am not going to pay because all my numbers are TOPUP. I even went into the shop to reinstate the topups in june and when I called mtn again on 28 Oct i was told the topup was removed from my one number on the day that I asked them to reinstate all the topups.<br> <br> by Monday 2 November if I do not have a solution for my queries I will start with legal action agains MTN
