Bad customer service and attitude

I took garlic that was priced R9.99 and other things when I get to the till point it was scanning a different price I told the cashier that the price is wrong she insisted that the whole day she was selling them with that price but I told her that I saw R9.99 and I want it with that money I asked if we could go and check the price she refused and said is the price that she scanned but I told her the price that I saw we spend 15 minutes arguing about the price all she told me to leave her till and go and pay on the other till point when she realized that iam not moving she then decided to call the supervisor I think her name is Julia she explained the problem and the supervisor asked her why dont you go with the customer she said she wants to go to the back then Julia told her that she should have just walked with me to the shelve and we check the price I walked with her when we got there the was lot of mistake in terms of pricing we found another cashier telling the guy that packs the garlic that they are scanning wrong prices we had 3 garlic that are the same with 3 different and wrong prices a we also had the other 2 from the 1I took with the wrong price Julia took the tag of the garlic that I bought and fixed it for me but the cashier decided that shes not going to assist me she started saying she wants to go to the back and leave her till to be operated by someone else basically she didnt want to assist me anymore I told her that iam not going to go anywhere until she comes to assist me when she realized that I was not joking that's when she came while we were busy with the whole situation she showed less intrest in what we were doing she was busy talking to her friend asking if she needed airtime while iam still paying so now she was nolonger interested to go to the back the cashier's at FOOD *****S MARKET at greenstone they dont have great customer service before the whole incident the first till that I went to they decided to help each other with their airtime when i asked they said they doing a refund for a customer while the was no customer that was standing there and needed to sign for the refund I was told to go to the next till where I had a terrible experience
