Tile Africa poor service

I purchased 38 m2 of 1st grade tiles from the Kenilworth branch. My tiler informed me that 5 boxes were repackaged tiles in a taped up box of different size tiles. I bought 1st grade tiles so I didn't expect to be given the wrong batch tiles. When I complained to the consultant she in a rude manner told me that my tiler should have checked the batch numbers. This is not my tilers duty to check but this should be checked when my tiles are given to me from the store. Customers please be careful when dealing with this store.
