Here is the fundamental mistake. This data is enough to calculate you in a few seconds, if necessary.Never highlight your real phone number on any Internet resource. Never. I recommend that you change your phone number (or better yet, your mobile operator), transfer all contacts to a new number, or eliminate the old number that has already been compromised, or use it as a "trash" number for online purchases, for example. I personally have a separate phone number and a separate smartphone for communicating with government and banking structures. In total, I have three numbers from three different mobile operators. One is for online shopping and other trash, the second is for chatting with friends and family members, and the third is closed to everyone. Only banks and government agencies. And I never use it for other purposes on the Internet. As for the e-mail, it's better to create a new mailbox. There is no absolute security here, even proton mail merges user data, but nevertheless it is better not to put all the eggs in one basket.
