KFC Complaint

Hi , Im a FNB Ebucks customer trying to spend my ebucks points at KFC .I phoned around PE Commerial Road ,Cape Road ,Cleary Park KFC branches to check if I can use my ebucks card to find out nobody knows about it ,staff said I can come to KFC and they will try it .Then I took a drive PE KFC Cleary Park ,Commercial Road KFC card is showing declined/ERROR .So the next day I phoned FNB to complaint why is it that nobody knows about it the call centre lady then told me I need to buy voucher online .Bought the voucher went over to commercial road they looked very confuse ,but try the card shows error .Very angry I left again went to try it at Cape Road & Commercial Road .Which Asanda at Cape Road knew about it ,but at 1st also confuse why voucher not going through ,went to someone at the back .Came back very helpful and said she will add some mails on she think I need to spend full 200rand voucher ,cause I purchase for less then the 200rand voucher. She add a ice cream and it went through .The next day the x2 coslow I bought with my meal were sour .What a terrible experience to use my points .(ebucks) KFC staff really need some training how the FNB ebucks works .They been helping the FNB ebucks clients ,but they don't even know the voucher they using is FNB ebucks clients .(They all look so confuse I even call the managers they just so confuse as their staff .
