Poor Account/Billing Support

I have a 2gb bolt on package on my MTN contract . On 07/05/2015 I phoned the Call centre and I spoke to Gnozi Bolani (ref 127 328 890) - if you can't find the recording I can source it for you . <br> <br> According to Gnozi, the 2gb bolt on is removable as it's not part of the initial contract (from Nashua) and she sent a request to the accounts department for the service to be terminated and credited and that we would have feedback within 2 days. I have logged onto MTN active and I see the bolt on is still active. I am unable to deactivate this online. Today (12/05/2015) I tried to phone MTN Contracts *** and as soon as you \get transferred"the call is ended"
