Outrageously bad support from call center staff

Before I left the RSA for the UK I set up my first Card to send my OTPs to my email address as my pay as you go phone does not do roaming. Last week I tested it and it worked. Today I tried to do a payment online and it kept sending the SMS to my SA phone. When I checked online I was told to go to a ATM or into my branch, I ask you with tears in my eyes how do they expect me to do that from several thousand miles away? After spending all my airtime holding on to the contact number I got cut off. So I tried using the online chat and I got the same advice or no response at all from 3 different operators. The conversation went like this "13:21:20 I have a problem in that the money on my phone has run out. This is the only access that I have at the moment. Barry Roper 13:22:21 My apologies Berry. How would you like me to assist you? 13:23:32 Due to not responding. I'm going to end this chat. Please chat to us again to get assistance." and this "13:29:00 Kindly contact Online banking for assistance on ***) 08:00 - 19:00 M-F; 08:00 - 17:00 Sat; 08:00 - 13:00 Sun 13:31:01 I DO NOT HAVE AIRTIME I WAS HOLDING ON FOR SO LONG THAT ALL MY AIRTIME WAS USED UP AND WITHOUT AIRTIME I CANNOT PHONE AGAIN AND I CANNOT BUY AIRTIME WITHOUT AN OTP NUMBER. 13:32:25 Please visit your nearest branch for assistance 13:35:02 PLEASE GET ME SOMEONE WHO KNOWS WHAT THEY ARE DOING.

" Dear valued customer â?¢ FNB :-) Online Secure - You are about to make an online purchase of ZAR4940.00 at British Airways using card no 6067, Confirmation OTP:4969. 13:50:36 The device that you are currently using is unverified,it has limited functionalities.

So Now I sit in the UK and cannot use my accounts to pay for outstanding debts or online purchases thanks to the inefficiency of FNB and their call center staff who obviously do not subscribe to their catch phrase "HOW CAN WE HELP YOU
