Rip-off and no one cares

I upgraded my MTN contract on the morning of 11 January 2018 at the Middelburg Mall in Mpumalanga. At that date I had an amount of approximately R550 left on my contract and I specifically asked the person assisting me whether this amount will be transferred to the new contract. He categorically said that it will be transferred to the new contract. It did not show in the afternoon and I went to the mall to seek assistance. The same person said I must wait a day or two and then it will reflect on my account.

On the 13 January it still did not show on my contract and I went to shop to inquire what was wrong. Another person helped me and phone enquiries (the number is 808). This helpline indicated that they do not have access to the history and will come back to me. Since then myself have phoned them on three occasions and every time I got the same answer. Unfortunately the first time I phoned I did not get a reference number but the other two was as follows (name and reference number):

1) Gladys number ********** 95 2) Dimakatso number 1- ********** 9204

The original reference number under which the complaint was lodged was 1 – ********** 2314 and my cell phone number is **********
