I have been waiting for respond or communication and pay back but reserved nothing

Unless I wrte a review hear I don't can an update yesterday after writing a review I received calls from two staff members from fnb both of the promised to get back to me but so far nothing.if FNB can allow anyone to access our funds without our permission and when we ask them they don't have ansewrs for it means our money is not safe with them.I ddnt know doing reversal for unauthorized debits was going to take for ever to reverse if they think by sending me pillar to post is their of trying to dodge paying back and think I'll eventually get tired and let this go no they are wrong FNB tell me the solution I make enquiries about this on the 30/11/2017 and so far your acting like you don't know wat to do like amatures they are other banks out there who take their clients Serious
