bad /unacceptable customer service

Purchased a new well known brand chest freezer, the unit was delivered to my home the same day. Upon inspection when delivered I discovered that the freezer was not standing flat on the floor and seemed as there was a missing part ( wheels or feet). I immediately when back to the store to report this problem to the sales person. I was informed that they will arrange for defy to come and correct the problem. The technician came out and checked the unit and informed me that the was no wheels or feet and he could not fix and I should go back to the store which I did. When I informed the sales person she told me that they would now replace the freezer with a new one. This all took place before Christmas, and as a result the sales lady said that they would replace after the holiday. I pointed out the store policy at the tills that any exchanges will only be done within 7 days. I was told that I do not have to worry as I have reported this matter the same day and the exchange will happen . Well when went back to the store after Christmas and I did so almost every day no exhange took place instead the store arranged for the manufacturer to come out to my home again with no fixes.
