Useless Service from Telkom and even more useless Agents working there

I’ve been to Telkom stores for every month that they didn’t Debit my account after they had done a Debi check on my account in September after I had opened my account and yet each time I go to their store they ask me for proof of banking and when given they tell me the information has been updated the come debit date nothing I have called the support team to assist and each time I call it seems I get an agent more clueless than the other keeping me on the line for 30min to update my details from an FNB account I never provide them with that I don’t know and waiting for a Debi check mandate to come the the cut the call. Useless I just want to cancel this service they have zero service.
