Unacceptable service and goods from Matress Factory

I bought matresses from Mattress Factory in Oct 2019 and by Dec 2019, they started collapsing. I was told that the factory was closed and that I should come back in Jan 2020, which I did. It was a long, huge flight, butt hey gave me a credit and forced me to purchase 2 new beds from them. It is now Nov 2020 and the 1 bed has now again collapsed and the inner springs cannot be avoided when lying down. I called headoffice and Ashnie , the regional manager called me back. She told me that the manager of the Boskburg branch, Jeanette, would call me and she did, a WEEK later!!!! She told me that she has placed a call with the Sealy rep to come out and have a look at the bed.

It is now another 10 days later and nobody has bothered to call me and arrange a time. I am not sure what one needs to do to get service and goods that actually lastfrom the matress Factory. It is just unacceptable.

It is nearly December again, so will I be told to come back in 2021?
