Just thought I'd share a letter to MTN 
To whom it may concern,
About 3 days ago I tried to make a call on my phone, and I got the horrific message 'you account has been suspended'
For what I thought? I get a good salary, they checked my credit, I haven't not paid, what could it be?
No, MTN decided to disconnect my service because I'm a new subscriber and my credit limit is only R1000. Who the hell thinks of this stuff? Do you think this is going to want me to stay at MTN? Anyway, I called the call centre, requested them to reconnect me immediately by debiting my credit card, I gave them all the details. 24 hours later, nothing still not working. Then I called again, the lady refused to help me and said that there was nothing I could do to reconnect this. And next month the same thing will happen again because my limit can't be raised from R1000 because i'm a new subscriber (great credit checking process by the way really!) If your credit department did their job correctly this wouldn't be an issue as it seems the bank trusts me enough to give me a home loan!
But now, I am so infuriated by this, excuse me for lack of a better word, C R A P service, and the costs to cancel this contract are exhorbitant, I am no longer going to use this phone at all, I will use the free minutes every month and the free sms's, nothing more. I do not want to give you one more single penny than I have to.
Where as you could have been making R500 a month from me at least you will get my R89 and I will take my minutes, sms's and handset.
I would like a response, but I won't get my hopes up.
Regards,
Donald
