Edblo poor manufacturing

I bought an Edblo - 7 Crown - Queen Size Bed - 188cm This mattress has a 10 year warranty. Less than a year later the mattress was sagging store decided to give a new mattress, in 2018 the base began to sage and the mattress also starting caving-in you could hear the springs each time you got onto the bed, I called bed direct to complain and they advised me that it’s not there problem I should contact edblo as my warranty with them had expired Finding this an unacceptable response as my warranty/guarantee was still intact I went into store to explain my problem, the gentleman in store after much persuasion understood and referred my matter to edblo who after months me chasing them and bed direct chasing in 2019 replaced both mattress&base with a supreme Madrid 188cm in 2020 I starting hearing the spring of the mattress and called bed direct who advised that edblo was closed due to covid and nothing can be done I must just rotate the mattress periodically the noises stopped for a few months however I am experiencing the same issues I had sagging base in the middle and sloppy mattress no one seems to be bothered to resolve this matter or look into the faulty base and mattress.
