Cancellation Request a Nightmare

MTN loaded me with airtime after i requested to cancel, i called numerous times trying to have my contract cancelled.I called for the first time on the 18th of March16. One agent would tell it would be done in 48hrs, the other 30 days and the next thing they can`t find my request to cancel up until i requested to speak to a manager. I spoke to Samukelisiwe Mdunge who assured me that this will be resolved ASAP.and the line was migrated on the 24th of March after i spoke to the Sam. Now the issue the airtime they loaded me with after cancellation which i did`nt use , Samukelisiwe sent me an email saying the airtime has been retrieved:<br> From: Samukelisiwe Mdunge [ MTN South Africa ] [Email Removed] <br> Sent: 29 March 2016 10:28<br> To: Gomomo, Nompumelelo<br> Subject: Re: Request for immediate cancellation<br> <br> Good morning Miss Gomomo<br> <br> I trust that yours was a rejuvenating weekend <br> I have sent a request for the airtime to be retrieved.
