this number called me at 5:40 am. i dont know who it is and it doesnt go through when i try to call back!

it called me too but I dont know who it is I think it is from outside the country

I received two calls at 5:30 a.m.  I didn't pick up the phone because I was sleeping, but it left me two messages with a lot of noise in the background.  Nobody talked.  I was expecting a call from a friend in the US, so I called back but it wouldnt go through.  When I got in the Internet to check the phone number I found out this has happened to different persons with the same number.  Should I worry about this?

The phone number with area code 993 has called me 7 times already, you mentioned that the real caller is down in Colombia, how did you figure this out? and who is this phone number?
i would appreciate it, thank you

This number has now called me about 6 times. The area code is from turkmenistan but the real caller is in colombia.

I'm now receiving my 27th call from this unknown number this morning

ESte nº me llamó hasta 5 veces a las 4:30h. Por lo que he averiguado es una llamada desde Turkmenistán

This number called me at 5 in the morning GMT+1, i missed the call because i was working!

This number called me twice at 5am in the morning.  I couldn't hear anything clearly, just a bunch of noise in the background.  I hung up, they called again with the same result.  Then I got another call that said Privacy Manager which had to be the same people just using a different way to call.
