Terrible service at telkom EastGate and Callcenter

On the 11th or 12th of May I upgraded, I asked the lady what the charges will be and I was advised that I need to pay a R100 upgrade fee, I paid the fee and asked the staff how my bill is going to look,<br> <br> I dealt with Cathy at this branch and she said that there will be no pro rata costs as I already paid for the month when I upgraded , I was advised that my premium will be as follow with effect from June R449+R649for the new phone<br> My account was said to be debited for R1098. When I paid the upgrade fee after getting the phone , Cathy then asked the cashier as well as the other staff if this info is correct and they advised me there will be no pro rata.<br> <br> I want this rectified , as I was then mislead, and should that be the case , I do not want this phone anymore, I called the East gate branch so many times however they never answer their phones I was told by a Call centre agent they will log a complaint and get back to me within 72hours , and that was almost 2 weeks ago, the manager at the branch is apparently Anastasia Steyn, however cant get hold f their branch at all, I need this sorted as I will not be paying R1691.87. if my account is billed by that i will take it further
