You will be punished for Telkoms mistakes!

I am truely dissapointed with my favourite service provider. My 2 year cellphone contract is almost coming to end and suddenly they stop debiting my account. I immediately phoned to inform them and I told them to debit my account double the next month. They agreed. The month came and went and STILL NO DEBIT WENT OFF AGAIN! E-mails were sent calls were made. I even asked to settle my entire contract. Then suddenly my number was suspended! I could not believe it! I had to drive 45km to the next town (my nearest telkom) to ask for a settlement letter just for them to tell me due to the arrears I cannot settle my contract which was Telkoms fault in the first place! Unacceptable! And after all this, the service consultant still had the nerve to ask me if I wanted to upgrade 2 months from now....
