I recently noticed a shortage on my bank account. So i ended up requesting my bank statement. To my surprise i found that ManhatMark, CB Marketing ,Khensani MG were making unauthorised monthly deductions from my account of R79,R89,R79. <br> <br> I was informed im not the only one with this problem, the people who are deducting this money from my account, bank with FNB Bank and are not traceable ,This is day light ***** i cant be paying R60 (R20)x3 for Nedbank to reverse this on a mounthly basis. .<br> <br> I would like to ask at this time, what is your plan of action Nedbank, This seems to be happening mostly to your clients. . What measures should be taken to stop this accurence<br>
