Telkom have NO idea what they a doing.

I am constantly being billed wrong amounts. I go into North Gate branch and Prudence(name starts with a P) tells me I must use the phone to <br> sort my issue out. So I go into the shop with a toddlers to use a Telkom phone because no one in the store can help me. I then have to phone and apparently it is sorted. And of course today I wake up and of co**** the wrong amount is once again deducted off my account. This needs to be sorted or I need to take my situation to legal advise as I cannot afford to do this every month !!!! North gate Telkom has a bad terrible attitude.
