Very poor service from Telkom Mobile. Can't resolve a straight forward issue.

I made a prepayment on the app and was told that "That's why you are our favourite customer ... Payments may take up to 3 days to reflect." 6 days later, a debit order bounced in my account for the same amount I had paid. Now, my account is suspended for several days even though I paid and confirmed that the payment is reflecting. I have spoken to several agents who simply promise that this would be resolved within 24 hours but nothing has been done to date. This is very poor customer service. I'm considering going back to Vodacom. So much for Telkom.
