Game has no regard of a contract!

I can not believe this just happened. We bought a RusselHobbs microwave @ Game in June 2015 and it stopped working in December 2015. We took the microwave back to Game since it had a 2yr warranty. The guy who served us said they could not replace it since it was over 7days but they could repair within 3wks and if its not repaired they will replace it. We left it on 16December 2015 and the form they gave me and we both signed states that it will take 3wks. My husband just went there and the rudest of them all Mangers Sindy Nonyama should nt be working with the public. She said the microwave was not ready and we shld start counting the 3wks again today because repairs center closes during holidays. When my husband tried to explain to her that thts not wat the form says and the receiving person did not mention the holidays, Sindy said \Its not her fault that the salesperson who took the microwave in did not explain to us that during the holidays its 6wks not 3wks"I am completely thrownback and surprised abt this attitude because I thot a Manager @ Game wld care that we're struggling with preparing food/milk 4 my 9month old baby without a microwave. Can someone who cares please help!"""
