Over billed

My bill for July 2015 thus far is R2500. On average my invoices is about R1040. I had a look at my invoice and found that my new contract has come into affect and my line was not closed but open. Jimmy neglected to keep my line as a closed line therefore when I reached my 2GB limit I was billed for data usage. My request to Jimmy was to make this a closed line which means that after the 2GB limit was reached I can recharge my account with a prepaid voucher.<br> A data bundle was added to my contract without my knowledge for a further amount of R229. I went to the Boksburg Branch to cancel this data bundle and was charged R65. I did not ask for this data bundle but had to pay to get this cancelled. <br> Furthemore on my contract I pay for a sms bundle but was charged for sms'ses.<br> I went from a MyCall500 contract to a lower option to try and cut costs but due to the fact that the staff at Altech Autopage not being trained properly this contract is costing me more than what I can afford to pay.<br> I hope that this can be resolved as soon as possible.
