WORST SERVICE UNPROFESSIONAL & FRUSTRATING

ABSOLUTE WORST SERVICE I HAVE EVER ENCOUNTERED. I have switched mobile devices the last month there is not a single person that has been able to assist me in getting the FNB app linked to my new device. I have spent a couple of DAY'S at the bank they are unable to help me they simply call the call centres which tells me to wait 24 hours it has been 2 weeks I am unable to do transactions on my mobile banking. I run a business this is very disruptive and unprofessional. I need a technical expert to contact me ASAP to get the problem resolved alternatively someone that can assist me in closing my accounts with FNB.
