Not satisfied with mattress purchase

I purchased a memory foam mattress from Groupon and what a shock when it arrived! It definitely does not look anything like the photograph in actual fact it looks more like a mattress protector and not a mattress. I am highly disgusted that Groupan can mislead consumers in this way. I have sold my original matress and now sit with the dilemma of having to spend more money on suitable mattress. I sincerely hope that Groupon will provide me with a refund. I will certainly never purchase anything from Groupon in the future! <br>
