Worst service ever!

I bought a shirt yesterday at Foschini and when the teller was taking the security tag off (with great aggression!) he ripped the shirt. He did not say one word to me and turned to another teller to get him another one. I told him that there was not another in my size. I had already paid by this point and asked him to source me a replacement from another branch. He then said I needed to pay R50 for an order!!!!!! I had already paid R350 for a shirt I did not have and now I had to pay another R50!! When I asked where the manager was I was met with silence from all tellers until finally I got to speak to the manger. I explained to him that I was more angry about the way I was spoken to - or should I say NOT spoken to than anything else. He also told me I had to pay R50 for them to get me another shirt - THE TELLER TEARS THE SHIRT AND I MUST PAY TO GET A NEW ONE!!!! Obviously a great way to get more money in the business. I am horrified that they did not sort out the problem and order me a new shirt at their cost and now I have to wait 2 weeks to get my money back!!!! Will be the very last time I shop there and will be telling all!
