|---|---|---|
| Ohio Bell (AT&T)AT&T's landline company | 198 | 25% |

- Hang up on anyone who wants gift cards, crypto or a wire transfer, or asks you to read out a code that was just texted to you.
- Report unwanted robocalls at reportfraud.ftc.gov, or paste a suspicious message into our free scam checker.
