System don't work - e-wallet

I left my wallet at home and realise I had to put in petrol. I called my wife to use FNB e-wallet to send me money to put in petrol. Received the sms with a pin number, when I got to the ATM it decline the transaction saying “an error occurred” you may have entered an incorrect cellphone number or pin. I tried 3 times and each time I got the same message. I left and went later to FNB at Craddlestone Mall. The same message, I spoke to a lady from the FNB branch, and she said if it says your number is wrong then your number is wrong, quite arrogant for a clerk. Two things, FNB is not so good anymore and despite them bragging about introducing more technology than any other bank maybe they should consider making sure it works before they brag. The arrogant staff, apple don’t fall far from the tree, remember the SAA saga. I am convinced if we reverse the transaction this FNB won’t return the service fees too. Time to change banks, less arrogant and more effective bank.
