Number blocked - Even after Payment made

I am not sure who actually take customer service seriously between MTN and VVM attorneys. Prior to my contract with them coming to an end i informed MTN that i will not be renewing the contract. this seems to have fell into deaf ears and i ended up with a bill of R1000. This resulted in my account been handed over to the legal department(VVM). I made a payment with them to settle the account. After following up with VVM i was told it takes two month before the account is cleared(I will not even get to the issue regarding their call centre that hanged the phone on me while trying to sort this out). Now VVm tells me my account is with MTN as it has been cleared from their side. Tried to call MTN legal department - their phones don't work. Spoke to a lady by the name of Kamogelo Mosome(who has been very helpful) - she sent a mail to the legal department for them to contact me...Its been a week now and no one has contacted me. i am sitting here with phone that is blocked although i have made full payment and MTN is still not responding to me. This really pathetic because when they call for payments they call day and night...this is REALLY pathetic service.
