Pathetic customer service by Telkom

I have experienced so many issues with Telkom fibre at home. It took about 4 months to get fibre installation done correctly after it was not done properly the first time. It took 8 months to get find someone to get account sorted out and a year for account to be correct (finalised). I have decided to cancel my fibre connection after 27 months and they could not get that done by the 31 August 2020 after giving a months notice (more than adequate. Case no ***7 (TIN); ***4 (B number); ***5 are unresolved. I would like to have the B number released so that i can get another service provider. I so regret having entered into this contract with Telkom.
