billing

I sign my new contact at the greenstone branch, for the amount of R439 with a 0 usage limit, I got sms to say I went over my usage limit and then I call the call centre and they said it was not done, the person that help me put thou a call for it to be sorted out. Then I also never got my February bill. When the Feb bill was sent me, I got changed an amount of R802 which is incorrect . it should of being R439 + R159 =R598,then I went back to greenstone and told them the guy by the name of Smangaliso sent any req for me, which was also not done because my account was debit for the incorrect amount R802.<br> <br> I call back the store and tell them they say the rate was not active on the network. the service is very bad and am very unhappy, the call centre can't help me and the store , how many more req will they log before the problem is sorted out.<br> <br> <br> <br> I need this to be sorted out with the usage limit and with credit back to me account.
