Mtn has the worst customer service ever!!!

I upgraded my contract on 9 April 2015 to a MyChoice 100 which costs R499.00 per month and includes 500mb, 200 sms's and 100 minutes of airtime. This contract has not been credited with this offering. I have been phoning 808 for a week, been to the branch Cresta twice and still no data, airtime or sms's and I have had no luck.<br> Your service absolutely SUCKS. If I don't pay my bills my phone gets cut off immediately but I can do nothing if I don't get service.<br> I am so frustrated that I could shout but that will not help me all that it does is make me unhappy and Mtn is not worth that!!!<br> I am so disgusted as a long-time user of Mtn and always paid my bills on time to be treated like this I feel so let down by the lack of service and care from this company.<br> Regards<br> Velette Welsford
