Pathetic service

I have been making manual payments for my cellphone contract since last year and I have informed telkom that I have been retrenched, so an agent suggested I make manual payments from my banking app (easy pay) which will take 48 hours to reflect on their side and changed my debit order date to the 15th of every month...Yet they were still debiting my account even after the agent said they won't debit my account once payment reflected on their side which was a lie! Obviously I am unemployed there is no funds in my account and now I'm sitting with rejection fees from all these ****ing debit orders which is so unfair... Last week I spoke to another agent who says they will still debit my account regardless if I make manual payments and it takes 10 days to reflect I am so ****ed off!!! I will not take another contract with Telkom ever again this is so pathetic I am now liable to pay all these extra fees which I can't afford yet my account has been paid before the first of every month!!!
