Home choice compromised the quality of the Capital Foam Mattress is now ,a SPONGE not Mattress

I bought 2 single bed with 2 capital foam mattress around May this year and it happens that the beds that they delivered was wrong and we had to return them together with the capital foam mattress. Home choice return procedures took about 2 months for my account to be updated and we had to order again 2 single beds with frame and the Capital Foam Mattress. The problem is the Capital Foam Mattress that was delivered for the second time was lightweight, the quality was not the same as the previous one. Home choice changes the quality of the mattress which is a sponge is no longer a mattress, the ''so-called mattress is very light". The problem is that we are stuck with singles beds with no Mattress, and refuse to take them back. Home choice is selling single beds that don't have a proper mattress of those single beds and force their customers to buy Capital foam Mattress( The foam Mattress are very light, they are sponges, not mattresses).
