Tile Africa woodmead. A disgrace

So I went to Tile Africa 2 weeks back to buy broken tiles for a project I am busy with at home. I got a very helpful gentleman who assisted quite well.

Today I went again looking for the same thing. I was charged Quadruple what I paid last time even though the package was way less then what I had previously purchased. What annoyed me from today's experience was the fact that the manager of the store(Some lady) and 1 of his staff where laughing at me when I was questioning this price. They showed no respect for me only contempt. They made me feel like they were doing ME a favor by selling me those. I have never come across such a behavior as a client.The young man was way younger than me but he was extremely arrogant and the Manager never saw it fit to curb the condescending behavior. TILE AFRICA WOODMEAD...please educate your staff that every client and every cent contributes to the success of the company and in ensuring that they stay employed.
