Horrible MTN Customer service!!!!

I have phoned MTN customer services for over a month to get my contact sorted out. Firstly you battle your ass off to get pass the automated voice prompts to eventally get through to a consultant after 10 minites! Then you speak to a different consultant every time repeating your complain EVERY time! Requested several times for a manager to phone me back,obviously to no avail! Phoned again today & off course their system is off line I must phone back in an hour. For 2 months I haven't received my minutes,only data. They owe me over 200 mins! Causing me now to buy & use MY own airtime. What a load of ****! NO service or feedback at all
