Not A Happy Customer

I went to Makro on Saturday (10/08/2024) to buy something that was on special. The special stated that if you bought two Johnie Walker Black Label bottles you would get a Tanqueray no.10 bottle for free. I was told that the Tanqueray is out of stock and that the special was while stocks lasted. Nothing in the store indicated that the Tanqueray was sold out. Plus the special was meant to be until the 26th of August.
