Hurt by the way I was treated

I am so disappointed and hurt by the service I have received from engen queensburgh convenience centre by pick n pay!!!! About a week ago I went to fill up my car and advised the attendant to please clean only my front windscreen after filling up with diesel as the week prior to that they used the cleaning tool on the boot of my car which causes damage to the paint and scratches however when I went a week ago the same situation happen with the same guy again. I had asked him the tool in your hand what is it for he responding saying for cleaning windows to which I had mentioned the other day the same thing happen and I had told him not to do that because of the damage caused to paint on my car. He responded in a funny way and said sorry, Been a reasonable person because he had said sorry I had left it as that. This morning I went back to fill up as this is where I always fill up my car for many years. I was assisted in such a pleasant manner by the lady that helped me however the same guy that said sorry the last time was standing on the right side of my car and talking to another staff member saying this guy with the yellow car got a big mouth and an attitude problem I then looked out of my car and looked at him because I knew he was talking about me. He looked at me in the eyes and saw that I heard what he had said to me and made it seem like if I can do something about it. Been it a prayer day today and in a hurry to work I left and did not say anything. I had called the manager once I arrived at work and advised her on my concerns based on what happen and have mentioned to look at the footage as well to see how I was treated as a customer which is totally *********. Upon the footage been viewed this confirmed what happen and how these guys made me like a joke as a paying customer!!!!!! I am a customer service trainer within my company where we strive on customer service excellence however never in my life I have been treated with disrespect like this. To think spending thousands a month on diesel and years of support to this branch this is how I was treated. Please look into this urgently and provide me feedback as I am truly hurt by what happen and my experiences. I have requested a written apology however this needs to be taken very seriously. Imagine being an understanding person and letting an issue go could escalate to this extent and attitude by an employee representing engen petroleum is unacceptable. Please contact me on *** or email *** urgently. Treating customers fairly should be followed as per international regulations however it seems there was no care or regard because that is not his car or problem if damaged. As a person who takes pride and ensures my car is always in an immaculate condition I am truly hurt that people cant even show respect or concern for the customer!!!!
