Very Disappointed

Im so disappointed. After the website said the mattress i wanted and bought was available, and the website clearly states their delivery in major cities is 1-2 days. 3 days after i purchase and a tedious follow up process, it seems like my mattress is not available now. and i have been online to the agent for 3 hours now with no resolution. I need the mattress within the next 2 days, the main reason i bought from here was that delivery is within 1-2 days. I either want my mattress delivered within the next 2 days OR i want my money back due to false advertising
