Rude employer

Went to the Greenstone branch last weekend to get some swimsuits for my kiddies, and I could not see what I saw online in the store. The sales lady looks like she did not want to be there and responded so rudely...Like she was just annoyed that clients are shopping at her store. She said that they HAVE NEVER sold that particular swimsuit in the size that I wanted. Then I logged onto Mr Price online and showed it to her...she then says that they are actually sold out in-store. No apologies. Nothing! So I left and went to purchase them as Ackermans Greenstone. Much better service there. #BlackFriday
