TELKOMS BAD BILLING SERVICE!!!!!!!!!!!

Im so disappointed with the service Telkom has given me the past 2 weeks. I have missed a debit as our payroll company was delayed with this back in June. I was then debited on July 1st only 3 days late. Which im ok with, thereafter I was debited again in July on my debit order day which was in time but debited twice the amount they took for June again. When I call to ask for refund they keep saying i need to wait 7 to 14 working days. As they will need their COLLECTIONS department to update it. They can see the money has been paid but still wont do anything to assist me further. Now my account is SUSPENDED for no reason of mine and no1 will answer the call! I hate this service, I have been a customer for the past 4 years and no issues but now I will think twice to continue, such a complex system and rules for a payment OMG its unbelievable. They so quick to debit me extra but dont want to refund me and on top of it suspend my account!
