Google Keeps Taking Down My Website Without Any Reason

My experience with Google concerning the publication of my website has been quite stressful. One day it’s available, and the next it vanishes without any reason given. When I attempt to get in touch to find out what’s happening, I encounter total silence—no responses, no assistance, nothing at all. Interestingly, when you’re advertising with them, their responsiveness noticeably improves. It seems that if you're not a paying customer, your opinion is overlooked. The identical website is live on Yandex without any problems, but Google appears to have an issue with it and isn't providing any details on what that might be. I really can't grasp how a company of this size can so blatantly disregard its users. I feel perplexed and quite exhausted by this erratic and unproductive process.
