Unknown charges and lack of feedback from RCS

I wrote this review on the 18th of May and still have not received any feedback on the costs from RCS. This company is such a ****, I'm extremely unhappy and disappointed in you. I just want to know why suddenly am I charged service fees for the account I seldomly use... Balance has been R0 since April but the statement showed that I had to pay R44 something in May, paid it now the statement shows R41 something is due 1st of June. Why is it that you implement these changes without keeping us clients aware. I don't want to pay costs when not owing I'd rather have the account closed than this madness!!!
