Bad service from Bloemfontein store

I bought floor tiles and noticed that one box had all tiles cracked in one line (same position). When I went to CTM to return it I was rudely told it was not their fault but ours, I was told we dropped the box of which we didn't, and if we did drop the box the tiles were gonna shutter. I have a picture showing how the tiles cracked. I was not happy with the attitude of the who I spoke to and I think his name is Hezekei.
