Debitted for the wrong amount.

I closed my account last year with Axxess because there was problems to provision my MTN sim card on the Axxess mobile data network. I originally app**** for the 4+4 gig data bundle but like I said I however cancelled due to the provisioning trouble. About a week a ago I decided to sign up because Jimmy from technical advised me that the provisioning problem was solved and this is true because the second time I signed up which was last week I had no problems with Axxess to provision my MTN sim card. <br> <br> The new problem now is that I was billed again for the old 4+4gig data bundle. I app**** for the 250+250meg deal for R29pm. Why was the old details from my previous package used again? I want the overcharged amount back please. I called this morning but accounts ladies are not very helpfull and I hung up. Another accounts lady yesterday promised to send me a email to say they will sort out my problem. Until now I didnt get a email. I loaded a ticket on the Axxess website but this doesnt seem to help either.<br> <br> Can I please get some help here. I really feel like a needle in a hay stack with you guys that just get ignored.
