KFC BEACON BAY MANAGEMENT

I decided to go to KFC Beacon Bay as it was close by and convenient. I had an ebucks voucher to use from FNB. I went inside as I needed to give them a wi-code number I received on sms in order for me to get a discount. They called the manager. I told her I had a wi-code to give her. She told me she cannot accept that. She needed a note from the bank that had the code on. I said that's not possible. She said she is not willing to take the code and type it in. Very frustrating as how do you argue with someone *********** and totally refusing to offer any help whatsoever. After contacting FNB during the week I was informed that they do not deal with notes. KFC are supposed to take code from one's cellphone. I think FNB are wasting their time going in with KFC. I now feel that something needs to be done about management and customer services involving Beacon Bay KFC.
