I phoned call centre on 16 March 2015 to cancel my contract for *** & ***. Agent informed all airtime will be lost, I cancelled the *** number so long as the *** is used for business, he informed me that I have to cancel this number before 5pm on 17 March. On 17 March I phoned the call centre again at 4pm did not get through to the call centre the call keep getting cut off, until 5pm for an hour I struggled to get through. Then the cancellation department was already closed, the agent said he will log a call and they will phone me back. I am still waiting and know I received the airtime on this number again. I am so glad that I am cancelling my numbers with Mtn because to deal with this service is very very poor.
