Disgusting service

I bought a SEALY bed on 30.11.2020 and paid full price. It was delivered damaged on 03.12.2020. I called Bradlows and spoke to Abel and Eunice said they will open a complaint on my behalf. On 08.12.2020 Patrick from SEALY headquarters called me I sent him a photo of the damaged bed. He said the call center will call me in 2 days. They called me and said it is not factory fault. I have then been following up with the Silverton branch but nothing has come out of it. On 23.12.2020 Abel said the factory will be closing and will open on 05.01.2021.I called on 06.01.2021 Abel said they will open on 11.01.2021.When I called on 13.01.2021Abel said his manager is on quarantine and I have to wait 2 weeks. I'm so sick of their poor service I don't want the bed anymore i want a full refund. Please help me.
