USELESS USELESS USELESS!!!!

In September last year, I was called & offered a data migration from the 5Gs for R250pm I had to 80Gs for R300pm, it was a deal MTN was running at the time and I was meaning to go into the store and enquire but I was called so I was quite chuffed that I was being offered it and all I had to do was agree over the phone. I do a lot of work from home so I need it. I took it & was told the contract/agreement would be emailed to me. It wasn't. Been receiving 40G for the same price since September & no number I call can help me. I'm ready to cancel both contracts I have with MTN right now. Call centre agents keep asking for my contract/agreement even after telling them I didn't receive one. I have been a client since 2009 and NEVER missed any payments or bills but I can't even seem to get answers or a problem rectified.

Why would you give 40Gs for R300pm when I know there was an MTN deal running at that time for 80Gs for R300pm. I phone & get sent to different depts each time, with NO HELP from any agent. Over a week ago I phoned 135 yet again only to be given the first reference number I've ever received from MTN and told I must phone back in 3 - 5 working days with the ref number and see where my 'case' is. I phone after 5 working days and nothing has been done and I'm asked AGAIN for the email sent to me after the offer phone call OR call their sales department and request the email. MTN just pushes everything back into the customer's court and doesn't take responsibility for anything. I want the data I pay/paid for. YOU ARE ROBBING ME! I'm done wasting my time on the phone for mtns stupid mix ups. Send me the data owed to me (40Gs x 5months = 200Gs) & correct the contract/migration agreement in place now!!!!
