Not happy with the service from Game

Second review about same issue "Game Store" Canal Walk sent my microwave 2nd time on the 9th February that's even more that 2 weeks ago no feedback what's so ever... they send me pillar to post when I call..I'm so tired of the same issue "28 liter Defy Microwave". If they can't fix it second time around why can't they just refund my money and I will be new microwave...I'm heavily pregnant this is stressing me out.
