you can't upgrade

Got sms stating I can upgrade. Called call centre and they informed me to go to any branch. Went to lakeside mall in beNoni who told me to tell the call centre to upgrade me as they WILL not help me. Called call centre again who told me to phone 10213. Called 10213 and they then told me to call only during the week and another land line number or go to the store. So now quickly tell me TelKom do you still want me as a client?
