Shocking service from MTN

I upgraded my contract last month to a 40gig contract R199 a month. It must have been loaded incorrectly because I received an sms to say I owe R1099. I called Mtn and a lady said she would sort it out for me which she obviously never did. I even forwarded the emails I had received from the sales consultant who upgraded me.

I paid my R199 and then get an sms from Mtn last Friday 13th September saying I still owe R900 and I will get cut off in 2 days if it's not paid. I went into Mtn on Saturday at Gateway in Umhlanga and all the sales assistant could do was send two emails to escalate the matter. My number was cut off today.

I phoned Mtn and after speaking to two different people I've been told that the sales consultant who upgraded me telephonically at Mtn Liberty Mall in Pietermaritzburg is the only person who can sort this out. I can not call him since my number has been suspended, I don't have an alternative number and I cannot drive from my home in Umdloti to Pietermaritzburg to sort this out.

I've emailed the sales consultant and sent MTN a message on Facebook and I've received no replies.

I run my business using my phone and this is completely unacceptable! The service I've received from MTN is shocking.
