Bad Customer Service and inferior product

I purchased replacement foam inners for my couch/daybed in January. I waited 8 weeks and when I collected the inners from the Canal Walk store, the inners were soft low grade foam. They sent their fitter Dougie to investigate & he agreed they were not the same as the original hard dense foam. I sent them back with Dougie and continually had to follow up on status. Lockdown happened & then when they finally reopened I had to wait a further 8 weeks for a new set to be delivered. Dougie finally delivered end June but they are still not the same density as the original inners and have already started sagging. I refused to sign the delivery note & made a note of my unhappiness. I have emailed the customer service and ceo@coricraft at least 6 times which absolutely no response or even telephone call from the customer service manager. I am appalled at the quality of the product as well as the manner in which they have not dealt with this complaint to supply me with replacement high density foam inners. I will not be recommending or purchasing any Coricraft items in future
