Who called from 2533444308

Repeated to call for 1 hour- I did not pick up, and they did not leave a message. Who is this company?? I was told that this company can charge you up to $7000 a second and there is nothing you can do! DO NOT SAY YES TO ANY OF THEIR QUESTIONS! THIS IS A SCAM!!!!!!!!!!!

Anyone here knows who this is?

It showed up on my display as INTL. NUMBER if that makes any sense.  Dialing back gives me a fast busy.

Was called by 244 344 4308, shown as  International call, but when I dialed it was a busy signal
