Taken for granted

I bought a base and matrass at home choice and it was sinking after writing a review they came and took it and they replaced it with another one which was also sinking they came to take the base and matrass on the 26 October till today I have not heard anything from them it has come to a point where I don't want the mattress any more home choice can cancel my *** and transfer the money I paid for the mattress to my other *** failing which I will request them to refund me
