what should I do?

Randomly a notification about "your phone number is now verified" from Google play service on most of my email account appeared

its from a number I do not know 011 **** ****

I have gone on barely any website and even when i did, I make sure to have a vpn on and ad blocker on (These website is confirmed to be safe)

no one other than me have my accounts

i don't know what else to add, So please ask me if theres some needed info missing

I have bad english so I'm sorry about that
