Bad customer experience and miss leading advertising on product

My review on Beares Furniture's My sales executive was phenomenal in creating and personally overseeing my sale Which I purchased in August 2021 Washing machine top loader Kettle, iron and toaster. Pots Laptops And most importantly I invested in a Restonic 152cm bed which I thought was a investment @14k Seriously this bed has been a mattress replaced as I complained that it hurt my back I haveade contact with Restonic who assured me that Beares will replace and be in touch I waited and after a week I contacted Beares who in turn also requested a video and footage of the pillow top bed faults which I gladly sent I am now another 2weeks later and very much in pain as my back now gets ointment rubbed on, I'm on pain killer which I didn't require I'm terrible sorry but I have posted on Beares Instagram and Facebook and today I received a inbox on Facebook with the hope of assistance If I had known this was such a expensive but bad decision I would have gladly kept my previous bed that I gifted someone in need with I'm highly iratated and disappointed Beares Claremont after sales service is in my eyes very bad.
