Staff attidute towards customers

I went to woolworths Parow sanlam center to exhache a shoe that has a fault at around about 3 on the 14.03.22. I had not slip as ypur policy stated that you will gladly exchange the item. I was not happy that I was interrogated as tto which store I had bought it which date and I was told they need to track it with the other store to realy see if the is a sale of such, that was a first for me as an account holder. The ppc goes and tell the teller to asks if I have a rewards cards the response of the teller was "I don't think she has it do the is no need to ask" a whole customer service saying that in front of a customer I kept quite and she went on with the sale asked me to insert my card as I was paying the difference cash I respond and said I do have a rewards card I'm an account holder, then she wants to take the card, train your staff not to Undermine woolworths clients. Your quality of service is going down with that attitude you have lost a customer in me
