If you call, tell them the truth. And then get another email address with a different company, a one that doesn't require a phone number, such as GMX, Lumail, ProtonMail, Tutanota, Yandex or Zoho. Or get an account with a company that won't share your phone number, such as Gmail or Outlook (I have accounts with both and I've never had nuisance phone calls).
