The phone rings just once, then stops. Curious. You’re tempted to call back. DON’T DO IT!
It could be a #pingcall, in which you are connected to an international hotline which charges just for connecting, along with high per-minute fees for as long as they can keep you talking. Caller ID will look as if the call is coming from 01, 02, 04 etc instead of the expensive 0 899. These charges will show up on your bill as premium services. (surtaxée.)
If this happens to you, send a text to 33 700 with the title ‘spam vocal’ and the suspect phone number, and you will receive an acknowledgement of receipt
For any phone fraud, ring 0811 02 02 17
Watch out too for a scam involving La Poste telling you they are holding a ‘colis’ or ‘lettre recommandée’ for you, and asking you to ring to organize collection.
La Poste say they NEVER call you, and your postman should always leave a note when something is being held at the post office.
