Why is the quality of Jason's wooden door so poor?

Jason's door is not good, the quality is too poor, and the service quality is too poor. I just renovated two houses and ordered their goods as soon as I saw that the price was moderate. Results: After 30 days, I was urged to send a set by phone. What is even more exasperating is that the colors are all wrong, which makes people angry. The other set can't find the measurement form at first, but later it may take more than ten days to get a reply. When signing the contract, it was said that the goods could be delivered in 20 days. Don't trust them. They are lying.
