Receiving a call from a weird or suspicious number like "+1(-1)" can be concerning. Here are some steps you can take:
Do Not Answer: If you're unsure about the caller's identity or the legitimacy of the number, it's generally safest not to answer the call. Let it go to voicemail.
Block the Number: After the call, consider blocking the number on your phone to prevent further calls from that specific number.
Do Not Return the Call: Avoid calling back the number, especially if it seems suspicious. Returning the call could potentially lead to unwanted charges or expose you to scams.
Report the Call: If you believe the call may be part of a scam or fraudulent activity, you can report it to your phone carrier, as well as organizations like the Federal Trade Commission (FTC) or your country's consumer protection agency.
Stay Informed: Keep yourself informed about common phone scams and tactics used by scammers to avoid falling victim to fraudulent calls in the future.
If you continue to receive calls from similar suspicious numbers, you may also consider enabling call-blocking features on your phone or using third-party call-blocking apps to filter out unwanted calls. Additionally, be cautious about sharing personal information over the phone, especially with callers whose identity you cannot verify.
