Who called from 5163231983

This number calls my house of the hook, morning, evening, night. It is IDT ENERGY COMPANY. I already told them their calls are unwanted, yet they bombard with more calls than ever before. somebody has to stop them.

I keep getting calls from this number throughout the day

They call every day and you cannot call back because you only get music!  Very annoying!

They call constantly and i want it to stop.

You can make a complaint with the FCC
