Unwanted telephone call scam

They call you at your phone number with a few rings and then immediately close the call.
Generally we call when someone calls us and we cannot answer.


It is often a call centre robot that calls automatically and if we do not answer after a few rings, it goes to the next call.
No problem, if you recall, your call will not be accepted.

Occasionally it is a scam. The telephone you call back may be numbered with special rates, national or foreign.
According to the law, however, the user must ALWAYS and PREVIOUSLY be informed about the nature and the cost of the service.
So it should be enough to pay attention to the voice that answers your call.
