I live in Bangkok, Thailand & today this similar number which is 312-000-00158288 called me in the afternoon. The person sounded like an Indian guy, but my mobile phone has not been great these past months & where I was at the time was had a very bad signal reception, so his voice & conversation kept on breaking on & off. I told him to hang on as I tried to find a good spot to chat, but after a few times he just hang up. I decided to call back just to see what was it all about, but the number was not found or did not existed.
Weird I live half across the planet & some weird random "Indian guy" just call me.
F those folks. If it were up to me telemarketa would have to give their name and personal phone number to everyone they call. We could return the favor by calling them when they're working, sleeping or driving straight toward a telephone pole.
