Telkom at their worst!

Up until now I had great service from telkom. This morning I woke up and saw that telkom debited R301 from my bank account. I am up to date with all my payments and am always on time. This morning I called them and they were not at all helpful. My account gets debited on the 30th of every month. I get paid on the 25th of every month. In May I got paid on the 25th as usual but had to close my fnb account. But paid them immediately on the 26th, before the 15th of JUNE! So this lady on the phone tells me I have been back logged so had to pay R301 now. I told this is nonsense! It is unacceptable I am canceling my contract. So she says we'll then you need to contact some or other number and pay them cancelation fees. I am highly disappointed in telkom! I've had this contract since 2019 and this is how they treat their clients. I feel they need to refund the funds. Never in my wildest dreams did I think I'd have to go through this. Technically speaking, they have taken food out of a person's mouth!
