pathetic service from store manager,unable to deliver undamaged goods,just want my money back

I purchased a queen sized Restonic bed from house and home east gate branch in November and waited a week for delivery when i got the bed eventually it was damaged i then waited a further week for them to collect and replace which they did but brought a even more damaged bed i called and they said they will deliver me a new one they waiting on stock its been a further two weeks now when i call they dont take my calls nor do they call me back , i want them to collect their damaged goods and refund my money immediately .I went into the branch and the branch manager Elize was good rude and blunt toward myself and my husband telling us how strange she finds our story as they sell thousands of beds yet only ours is damaged ????How can you possibly ask customers such questions ?All i want from House & Home is to return my money .
