Annoyed!!

I have been waiting for four days for assistance from FNB, this is not the first time either, this time I purchased a electricity voucher and accidentally sent it to the wrong number, the only response I've been awaiting is weather I am able to retrieve the voucher number or not, FNB has gone to extra extra measures to ensure that you do not under any circumstances speak to an actual HUMAN BEING until you are at you wits end!, every time I've needed to do something I've had to go to a branch and wait hours and hours in order to get any kind of assistance (During MY working hours no less!) the banks are filled to the brim with people who need assistance and the poor tellers are overwhelmed! Because there is no help to be found on the APP as they love to advertise and no help to be found on a call either because you'll be speaking to robot(of course!) absolutely regret changing banks, my last name at any atm is incorrect as well! The list goes on!!!
