No service as soon as there is a fault with your mattress

If there was a zero star I would have chosen that, because they have zero service and there quality beds are bad. I bought a Cloud nine bed from them in August 2020. Then early 2021 the mattress started saging, I placed a complaint I think in June maybe, but early July I still haven't heard anything from them and I then tried to get some responses from their website. The whole process is still going on, with me having to constantly follow-up, because they just don't get back to you if you don't enquire what now, what is going on? Absolutely unacceptable, do yourself a favour and buy somewhere else. Save yourself the trouble.
