Frustration to the highest degree, ON AIR Billing Dept awful service.

I spoke to Shwabha, (pardon the spelling, she was so impatient, could not get proper details), today , one of their many people i have contacted before. I am disgusted with the kind of treatment On Air TV, is subjecting me to. I gave them my Capitec Bank account to institute debit order instructions from.This was last year August,2023. They debited end of September 2023, thereafter, redirected debit order to Tyme bank account. I have on numerous occasions raised this issue with On Air. Every month, without fail, they send debit order to Tyme Bank, which is not for debit order purposes, and funds are not sufficient in that account for such, I end up paying fees for unpaid items.Then ON Air has audacity to send me messages about unpaid debit orders, when they are the ones not debiting the correct account. . How long does it take to update debit order instructions, Is almost six months later, their billing department is still unable to get this right! i asked for a statement on this account, i am told, their system is off line, they can only refer to billing department.Is this in line with customer protection ACT. I am being abused by this service Provider ! How else can i get ON Air to implement correct debit order instructions, and why they never provide account statements?
