Complaint / Horrible Client Service

I visited Mr Price at Waterfall Mall yesterday. First when I asked for assistance with the pricing on a shirt that did not have a tag on, I was told to go and look through all the shirts to find a price I felt this was not the way to treat clients. I have been going to the same Mr Price clothing store (Waterfall Mall) ever since I moved to Rustenburg, and yesterday was the first time I have ever had any problems. The cashier was extremely rude, constantly interrupting me and insisting on how wrong I was with everything I said. After a few minutes of rudeness, she stated that my signature on the slips did not match the one on my card (it looked EXACTLY the same) to which I offered up my ID (first time), and was ignored. She then proceeded to call the manager, and ask her opinion on my signature, which they concluded did not match. I offered up my ID a second time, and was ignored a second time. They then called another cashier to ask her opinion, which was of course that they did not match, and was told "see ma'am, 3 people have now said they don't see the same signing". I was in no way arguing with them, I had already offered my ID TWICE, so I stood there in shock and humiliated as there was quite a lot of people in the store. The manager then mumbled to the cashier helping me "just check the ID" and walked away. My cashier took my ID, looked at it for a full second, gave it back to me and that was the last contact she had with me. She put my packet of clothes I had just bought and slip on the desk, and proceeded with her next customer. I had to decide for myself which slip was mine to take, because she refused to acknowledge I still existed. I am completely disgusted with how I was treated, I have been warned about the Waterfall Mall Mr Price, I have heard of many incidents with the security and cashiers treating people like *******, but I have never personally had any issues with them until now. I am very disappointed, and am really considering closing the account because I don't think it is worth the trouble, and it is difficult for me to order online. I am surly going to warn all my friends and family about the horrible service Mr Price has at Waterfall Mall.
