To over weight for my new bed

Bought a washing machine new double bead base set headboard and side cupboard on the 22.07 2020. Paid all cash. Washing machine broke they came to fix that. Bed also broken. Been five weeks now waiting for new bed. Branch manager never available to talk to and every one else say they will phone you back but never do. Had to find out this bed only takes 80 kilograms. So it has become clear this will be an ongoing problem as me and my wife weigh more than that. Had they shared that info when we bought it I would not have bought it. 16.02.2021 they phone back to say they will deliver a new Matress on the morning of 17.02.2021. It is now almost 4 in the afternoon and still no bed. Let alone they day taken off to wait for it. It is now clear I will not put my foot back in house and home green acres and will make sure all my friends and family won't either. So when the new Matress comes and it brakes again I will go threw this hole exercise again as I am over 80 kilos and apparently my wife and I are over wieght. A refund is imposable because when u ask why the weight limit was not shared to u, the customer is wrong and the sales person is always right. When u speak to a manager in a higher position he calls u dude. So customer service don't exist and you Mr customer is always wrong.
