USELESS & UN-HELPFULL FNB

I am abroad and my phone packed up so cannot access the banking app linked to that device so cant do online banking. My card expired so a new one was posted but now FNB insist I go into a SA branch to activate it! I have made over 35 calls to callcentres with people who do not know what to do and dont want to assist so it is easier to pass you on to another department. My mother has been into the bank to try to assist only to be rudely told to go away they cannot discuss with her. I cannot get to speak to anyone in management to help, they simply wont provide contact details! I am now borrowing money from friends and FNB could not care less!
