Not Bothering to get back to clients

I phoned into the MTN call center asking for a number to go onto prepaid and I was told that this can not be done on a Saturday but the agent gave me a reference number and told me that it will be sorted out during week. I then sent an email out on 1 April 2015 to [Email Removed] and all I received was their automated response. I have had no correspondence from MTN what so ever and I phoned over the weekend as I work in a call center and I can not hold on for 30 minutes plus to be put through to an MTN agent. Their client services is shocking. At least Telkom send you an SMS to let you know that they are working on the problem. MTN leave you high and dry.
