Terrible Service

I called the call centre to cancel my contract and to give notice to cancel my 2nd contract for august, specifically asking if my current airtime will remain and for me to use it as prepaid. The agent, Cebisile Nkosi said it will and i made her repeat this and asked if this is voice recorded, she agreed i will not lose my airtime and i dont need to do anything, the switch will be automatic. Call done 21.07.2015 at 2.40pm. Ref *** and ***.<br> Now both my contracts have no airtime or signal. <br> Then i get a call from Brad Buthelezi who tried to sell me a retention package then said with shocking service, that he could not assist me and cut the call because my contract is cancelled. <br> I need someone to sort this out???!!!!! This service from MTN is shocking, i have been a MTN client since 2001.<br>
