Service suspended with reason and not getting feedback when asked why.

In June I had sent through an email to the sales team wanting to upgrade my package and also get another package on MTN. Well no one bothered to contact me until I sent through another email in July and that's when someone contacted me and had the upgrade done and also new SIM on MTN which had to be delivered. As usual I received a statement to what I had to pay for August. All and fair an amount of R495 was paid as per statement and to my surprise, 2 weeks later I receive another email that an amount of R356 was outstanding.

I sent through another email to enquire what was that for. A lady then contacted me but she couldn't really explain herself but then told me that the amount was recalculated and I now had to pay R206. The one question I had asked her is that if a package was given in the middle of the month and the benefits are pro rated, why do I still need to pay the full amount for the previous and current package, and she still couldn't give me an answer and after it all, I confirmed i will pay the R206 the next day, which I did.

Last night I then received another email stating final demand of payment for R149. What this for I asked??

I then quickly responded to that email requesting someone to contact me and explain. And to my surprise when I woke up this morning, my services were suspended, which is now an inconvenience to me. I then had to buy data so that I send another email which I included Cyril Xulu, Aloysia Kaynie, Anri Louw, Christelle Va and May Korff and none of them has contacted me to this very hour.

I can't begin to express my disappointment in service ever since I requested the upgrade to my package. And another thing that puzzles me is why I have to pay close to R850 whereas my upgrade is about R290 and the MTN package R159. I've never received such bad service since being a customer for some time now.

I still need an explanation to all these amounts I'm expected to pay and need my services reinstated.
