Google Contacts Suddenly Deleted From My Account

While using my Google account on my Vivo 5G 27 phone, about two months ago the phone numbers stored in my contacts and some of my information suddenly disappeared. I also believe Google stores all of my data, which makes this situation particularly concerning and has caused me serious inconvenience. Since I frequently change phones, I have used multiple accounts over time, but the account I am currently using and experiencing this issue with is e************@gmail.com**.

Because the phone numbers linked to my Google account suddenly disappeared, I have been unable to reach many of my family members and work-related contacts for quite some time. Experiencing this kind of data loss without any warning, notification, or explanation has put me in a difficult situation and damaged my trust.

I request that Google review the contacts associated with the account e************@gmail.com and restore my phone numbers in full if possible**. I also want an explanation for why my data was deleted and a resolution for the inconvenience I have experienced.
