an important called for me

This number called me about 3 times so far always with a different called id name, suc as v102322421650000 or other variations but same number. never picked up and never leaves a message.

I have received over 19 calls form this number today, When the phone is answered there is just an empty line any further calls from this number will result with the authorities looking into it

I have done my research now and I have found who this number belongs to!
