Worst Customer service Ever !!

I'm a regular customer at Food *****s market and yesterday I decided to visit the castle gate branch which is 22km away from me and honestly NEVER again !! Worst experience ! Cashier was absolutely rude not helpful at all & no manners in talking, attitude and clicking her tongue at us rolling her eyes when we queried an item very ****** talking about us in another language which lucky my husband understands and this was after we spend & paid already R1900 in this store we called the manager to relate what happened he apologized and said it was unacceptable and the audacity of this Cashier infron of the Manger yet again was rude to us even the manager was shocked I refused to take the goods and asked for a refund since the store did not need and value my business they stood and looked and me and said no it ok no need for a refund. I was so angry and disgusted I just wanted to get out the store. The manager promised to give me a call but upto now nothing ! This is how customers are treated and it just slides coz our business is not valued clearly and we as customers are definitely not respected !!!
