Poor Ridiculous Customer Care & Refusal to Replace Poor Quality Beds

I bought 2x 3/4 beds for my daughters thinking I'm investing in comfort but I'm very disappointed because the beds are wabbly, the springs are poking out and they make noises. I've been trying to get these beds replaced since August & it's ridiculous how these people treat their customers. I feel like I'm dealing with corn artists and ********. I went to the store 100xs, I called, I sent messages on their Facebook wall and inbox but I'm always told that they will get back to me THEN they claim that they can't get hold of me although I gave them 5 of my contacts details. Their delivery people came, they took pictures and to this day I'm still struggling to get assistance. Can someone please help me resolve this because I really had it. They are probably thinking I will stop asking for replacements but I WON'T because I did not spend papers buying those beds, I spent my hard earned money CASH. I regret the day I walked into that shops because my girls are suffering and I'm worried that they will get back aches and pains thats HOW BAD THE PRODUCTS ARE
