False advertising

The store in Durban on Umngeni road, I went to purchase a jersey that was on sale for R700 as stated on the tag. When I got to the till, they tell me it is not R700 but R1000 and I tell them that is false adverti*****t. They still insisted to sell me for R1000, do not buy from these guys as the false advertise only to get to the till and tell you a different price.
