FNB loves "Mac and things"???

Numerous clients have reported unathorised deductions by " Mac and things" , you would think FNB would have been proactive by now and investigated and advise customers about this as in my case the deduction was only R84.99 and would have looked over it if my daughter didnt have a huge amount deducted from this same company and brought my attention to it!!!!!!!!!!!Please reverse the amount and protect our account. It is not fair to have to block the card, reissue the card and wait!!!!!!!!!!!!!!!!
