Westham on the go

At 14:05 today I purchased some edibles from Westham on the go, a store based within the Shell V-power garage at Westham in Phoenix, KZN. I had my card in my hand to pay about to insert into the FNB machine on the counter and purse in my left hand. The machine suddenly says it's approved which was quiet surprising to me as I hadn't even inserted my card. I asked the cashier and with attitude she just said that I had tapped my card. I checked the card numbers only to discover that it somehow managed to tap into one of my kids cards that was behind another card in my purse. The cashier was very arrogant and just said "well, what do you want me to do?". This was her attitude and even ignored and never did give her name, which I eventually got from her supervisor. Her name I was told is Ketiwe. Needless to say, the machine obviously has a problem as that should not be happening but more th a that was the attitude of this cashier and backing her up were some "regular"customers from around there. The day something happens to them is the day they will realise, unfortunately that's the way things are today. There was one sensible gentleman there though , a Mr Adam I think he said his name is, an African male who said he is in charge and apologised on the cashier's behalf and said he will call FNB as that should not be happening. Very bad attitude from the staff of Westham onthego store
