FNB AND TELKOM - NO SERVICE

In Feb I ordered a sim card from Telkom @ R99 per month - all was done online as I do not have transport to go to a telkom shop. I asked them to port my number. After the sim was delivered I waited 24 hours and still the sim was not working. I phoned them and they said the sim was not setup and I had to go into a branch to port my number to Telkom. I then told them to come and collect the sim - as this is not what I ordered. never heard from them again until lockdown they started deducting R514 from my account. I disputed the debit order and they kept on deducting this obsurd amount which does not even make sense. This is the 3Rd month Telkom deducts R110 on my account - along with my service fees. I have queried this and the lady I spoke to just told me TELKOM DOES WHATEVER THEY WANT. You cant stop this service fee, you cant stop their debit orders - they will just keep on changing their references and or amount to get their money. I was actually advised the best option is to close my account. Telkom deducts this debit order on any date they please and this also inflates my service fees and the fees for non payment! When you call FNB they simply cant reverse the debit order - they cant help you in the branch and refer you from chat to phone and vice versa. How can FNB just allow telkom to deduct service fees from your account - which cant be reversed??
