Account not in arrears but locked without alerting me

Greetings

Im sending this message out of frustration. I had to find out at Telkom that my account was locked. The person who signed me up on the new contract did not increase my credit limit and my biggest frustration is that, im currently writing exams and I use my WiFi to access my lecture recording and my exams are done online. Telkom personnel checked and they saw that i was not owing Telkom. I then had to organize another Sim card at Pep because the consultant could not give me a new Sim card which puzzles me as to why not.

How am I going to study coz my whole life is at stand still?

Why didn't somebody pick up the phone and alert me that there is this issue, why are you suspending my service without alerting me as a customer?

I have invested time, money and energy on my studies, I cannot afford to repeat these modules next year. It will cost me even more.

I need this account activated as in yesterday...
