Edgar's Baywest Brent Peter's

I visited the Baywest branch yesterday evening and was on my way to the till when I noted that it was 17:55, on my way to the till I saw an item and looked at it, then one of the ladies reminded me that they close at 18:00 I told her I am aware. Got to the till was not greeted by the cashier Brent Peter's, his words was "you can come" put down my item and was asked do you have a thank you card of which I said no. He rang my item up and when I was about to pay I noticed that it was the full price and not less 50% as advertised, to my disappointment I said okay leave it. I walk around the corner and asked one of the ladies in cosmetics, if I cannot shop on the sale items if I don't have a thank you card, she said they could link and register me with my cellphone number. I went back to the Brent and he seemed annoyed and said I didn't say anything about my cell phone number. Now don't get me wrong, I don't work for Edgar's so I am not fami**** with what they offer. But every other retail store I go in they ask for your I. D number or cellphone number for rewards. Not this guy, no customer service, no interest in helping. He asks for my contact number of which I asked for his name and surname first, at this point disgusted in his arrogance. I give my number he turns the screen and in a heavy tone says "and now you will blame me for this" the screen shows I am not registered of which I know hence I came back to register with my cellphone number but due to his arrogance he could not comprehend that. Again I asked to be registered and then he took down my details and I said never have I ever experienced such customer service. They rushing to get home and not interested in servicing their customer and wasted unnecessary time. His attitude was appalling. After the transaction I thanked him and he couldn't even say you welcome. Is this type of people Edgar's employs?? That have no customer interest and interaction and cannot even greet their customers...
