I have been getting daily phone calls from a Dominican number (says Santo Domingo Claro) and when I answer there is no one on the other side of the call. This has been going on for months, 4 or 5 times a day. I'm wondering if there is any way to find out who is calling. I know you have to have a cedula to open a phone account with a Dominican carrier but how private do the keep that info? Sure would be nice to know who's calling.
