**** service and no resolution

My husband and I purchased the buy 1 get 1 free offer at Edgar's last week for the Pro action takkies on sale, a pair of size 9 and a pair of size 8. Came home to realize they had attached a size 8 and 7 together. How on earth does a store do that. I went back this weekend and there was no stock and they refused to refund or make a plan on the pair and there was no stock of any other size 8's in store and we had already given the one away as a gift. The lady at the returns counter said Westgate has stock and she placed the order to get one delivered to Cresta Edgar's which took almost 45minutes to do, making an almost 9month pregnant woman wait in the heat as the aircons don't work in the store. I get an SMS today to say they cannot source the item and I must call them back! *** shouldn't you guys call me back to resolve the issue? Disgusting service!
