False advertising about delivery times

I saw a bed online which was labeled as fast shipping, meaning it'd arrive in 1-3 business days according to their site. This did not happen! The first customer care people I spoke to had very dismissive tones. The next person I spoke to laughed at me and asked why I would buy a bed online if it was urgent. So they false advertise and somehow it's the customer's fault for believing their lies? I dunno how many people I called and how many empty promises I was given but buying on their online platform was not a good experience. They need to go back to the drawing board when it comes to their online service. The bed is great quality and super comfortable but their online service needs an upgrade.
