Bad attitude to customers

I went to one of your stores in North coast of KZN in Ulundi I wanted to buy and do the cash back I waited on the queue I think about 10-15 minutes when I get to the till the cashier said I don't take cards then I asked why you didn't say anything and why there is no sign telling us not to come to your till she said am not taking the cards with an attitude I saw that she is fighting I asked her to call the manager she said she can't she literally refused I asked her you can't or am not hearing you correctly she said I said I can't am at the till I asked can't you call someone to call the manager she said no that was the first time in my customer service experience I saw that kind of service from the cashier and the customer I have managed to get to the manager and I have told him my complaint and I have left my details for an update that girl she really not at SPAR to serve customers she is there for salary as she is at the front of the store she is the Brand embassador but from what I saw that lady is chasing the customers I don't know how many customers did she chased away today with her attitude she is not the right candidate for that position please review her hiring process I doubt the interview was conducted can i have a feedback on this
