Dissapointed customer

Marko poor service, Yesterday I was at the Makro and viewed a TV. Spoke to the sales man and he offered me the TV at a certain price. Gave me all the details about the tv. I told him I am going to get my wife and we will take it. When I came back the price was changed. I asked him you gave me one price confirmed with me and now when my wife and I here to take you increase the price. I was too embarrassed to even argue with him with so much people around, Surely you knew you settled on a price with me and I had to go get my wife, why make me feel embarrassed, like a fool in front of people and tell me something else. I had my son with me and you had 3 other people there with you , even the guy from LG. I am disappointed and will never want to buy from Makro anymore. Makro should stand by their principles if a price is agreed surely it should stick. disappointed customer.
