Billing?

(I have already posted this but seeing as no reply in over a week I have to waste more time. What a joke of a company)<br> <br> Good Day,<br> <br> Firstly, I tried calling. And as you probably know quite well, was a waste of time.<br> <br> I recently upgraded my contract with you after never having an issue, I upgraded to the Note 4 for R559 a month, today I receive a bill for R787.98<br> <br> So from R559 to R787.98, how does this happen?<br> I see there is an upgrade charge of R92.10 which nobody told me about at all during the whole upgrade process, other than that I am paying 14% tax on top of R599.12 cents, how is this possible after signing a contract for R559 a month?<br> <br> So paying R683 for a R559 contract is ridiculous!<br> <br> I would like this issue sorted out as soon as possible, as I should not be paying a cent more than R559 as far as I am concerned.<br> <br> Please contact me on ***, the account number is ***<br> <br> Regards,<br> Matthew
