Incorrect debits and additional charges

I wish you had minus stars, I have never been this frustrated with a company, I have been a loyal customer for the last 10 years and in the last few months I have had to suffer triple debit orders and then I get charged when they don't debit the correct bank account. I've lodged a case to have the amount reversed and I keep getting told that my account is up to date. It is up to date because I had to make manual payments. I am not arguing over the R70 additional charge or the multiple declined debit orders I had to pay for because of the incorrect account being debited. This boils down to principles and the bottom line is that Cell C is just full of **** and keeping your customer happy is irrelevant to you. I guarantee that as soon as my contract ends I am moving my business elsewhere.
