Out of stock and lies there after

I bought stove, hood and oven (Defy) on the 12 December 2014 and was informed that oven was not available and only the one an display was available. I refused the displayed and opted to get it the following year 2015 January 1st week, they agreed. January when I got at the shop, I found oven still not available but they went to the back store room and found one that was not new, why because it had some bend on a top cover of which I refused to take that one. I then later on after about two to three weeks, called the store from the other game store to advise them the other way they could use to get my oven quicker, they accepted and said they would be in touch. They never until such time I called the store again early Feb 2015, when sales person involved says that my oven was ready for collection and that I should come the next week to collect which I did but only to find that the oven that was ready for collection was the same oven I refused to take due to defects that were clearly visible (Bend). I immediately requested to speak to the store manager, when he came after about 20 Minutes. I explained to and he promised to get back to me soon, and up to now am still waiting for him.
