Telkom ****ming contract

I am currently having the most horrible experience with Telkom as I am supposed to have finished paying for my phone contract but every time I am getting money increased on my account and no one has a straight answer as to why. If I go to the store they advise me to call the billing department and say they cannot assist me with answering about my bill it's not their job, if I call as instructed they don't have a straight answer, one will say I need to make my payments 10 days before my billing day as I have advised them that I am currently unemployed and not receiving no money on my account, the other one will say 7 working days it's really confusing. But I've been making my payments the whole of 2023 manually and had no issues until December, January and February. Now it's like if I call or go to the branch to query about this my bill goes up and no one has an answer, all they say is "oh its penalties since we tried to debit but didn't get money on your account" while I have made a payment, sometimes they say "oh it's reflected that you paid but I think it has not updated on the system “. I am really exhausted by all this because I do my end to ensure I pay, as someone who is currently unemployed it's depressing to be also contact by collectors as if you do not do your part. Telkom is just putting me through the worst and it's so annoying when you ask for a manager and be told to hold the line and they will put you on hold for an hour and drop the call, sometimes it's 30 minutes than you get the manager who will be going on like a robot not allowing to hear your query. I have paid enough money to telkom and they still charging me more. I've just been to the branch in pinetown and was told to bring all my receipts so they can maybe help me. Anyone thinking of taking anything with Telkom, please think twice, I've had it, what's sad is no one is willing to help coz at the store they tell me to call billing department when I do they have no answers. The agreement was they debit on the last day of the month but I am sent notifications that they also tried to debit even during the month and if no money is available they add penalty fee. It's absolutely ridiculous and is anyone can please help me on who I can contact to help me resolve this issue and terminate everything I have with Telkom I'd highly appreciate it
