Very disappointed

After spending a fortune, I was really excited to receive my new mattress. I really thought I had finally found something that could let me get some much needed rest. Having dealt with severe back problems for years I was looking for something pressure revealing and comfortable. The first few days were alright, but after a week or so I started having severe neck and back pain, much worse than before, and was up tosssing and turning all night. Now the mattress has softened up so much that it feels like I am sinking in, and rolling into the middle. It feels more like my old memory foam than latex. I am very disappointed and have barely slept in 4 weeks. I dread going to bed, because I know I will be tossing all night. I have even tried taking sleeping pills just to get me through the night, but I still have troubles sleeping because of the pain I get in my back from the sinking in. I was told that latex should never feel like it's sinking in, and should keep its form. But this is not the case at all. I am now broke from the cost of the mattress, am not sleeping at all, and just wish I could get my old bed back. It was uncomfortable, but not nearly as bad as this latex mattress. I tried contacting the store I purchased it from, but I was told to contact Latex bliss. I have been trying for over a week to get a hold of someone, but no one answers. I emailed in, but one lady told me to contact the store I bought it from. I have been getting the runaround, and am extremely frustrated. No one can give me a straight answer, and just keeps passing me off to someone else. I just wish I could get my money back, or some kind of exchange.
