Poor service

I’ve been dealing with one issue for the past 8 months at Standard Bank where they are allowing MFC to debit my account without my permission. I’ve even moved my salary to another bank. Every now and again they will debit whatever amount and leave me with a lot of charges. I’ve spoken to their complaints executive Herlen Aldred and Strimling and they asked someone to assist. That person who was assisting told me that she had suspended MFC and I mustn’t worry about them anymore but the moment I deposited cash, MFC took it. I’ve emailed Standard Bank there was no response. Last time it took 10 full working days for them to get back to me and assist me after 20 emails.
