Got a call from 00 34 000.... They just hung up. I am convinced this is a fraudulent number

I recieved the +34000 call today (Wd 28/04/'16, 15:00u. during daytime) in the Netherlands..

Mystery continues...

All I know is that it's a Spanish number... I was rang by it at 2:30am!!! It woke me up and I was so confused! Probably trying to sell me something!!!

Today i was also called twice with the 34000 number, when i looked at the comments here i noticed that it is going on since 2012,  seems like this number is 'stalking' people for years! unbelieveable.. its not the first strange number that try to call me, also the numbers: +1 683-405-2206 /+31 10 742 0277/+31 40 244 8460 and lots of private calls..
It started around januari the 6th, and been called about 20 times till now by different strange numbers, before that have I never been called by a strange number..i never give any kind of persenal info on internet so i find it very strange but most of all very irritating! And it seems like nobody can do a f*cking thing about it! I have and will not pick up the phone when a strange or private number is calling so hopefully one day they gonna stop calling..
