Telkom pathetic service

I renewed my contract in December and my debit order date is set for the last day of the month. From January Telkom has been debiting me at the beginning of the month. After filing a dispute and contacting customer service, the issue has not been sorted out. Now i am not being debited at all as telkom says that the bank has not approved the debicheck mandate, which is absolute nonsense. I have been to the telkom store twice to approve the debicheck mandate. Now Telkom has blocked my account for being unpaid when the issue is clearly on their side. I have been paying my account on the telkom website and the website clearly states that my balance is R0.00 but the account is still blocked. After calling customer care i was told that there is an issue with the system and they will call me back in 15 minutes. Its been more than 24 hours and I am still waiting for that call.
