Winners Supermarket Unclaimed

It's a community store that been in existence for 31 years. You have to congratulate them for that,But where their customer service is concerned they will have to work on that seriously if they would want to keep their business for another 31 years,on the 29/11/15,I decided to shop there and bought meat there,it then according to them had incorrect information on there,I then told them that according to consumers legislation the price the consumer see is the price the consumer pay,Mr.Khan then impolitely told me that he is not going to give it to me for that price as it was a finger error and he does not care about the consumer act,I reminded him that it is not customer service like and inappropriate for a owner of such a business to behave in such an inappropriate manner,the supervisor also came along and then told me that I am the one being dishonest and told me about my religion and eating then haram food,I believe that that was not their place to tell me about my faith.
