Who called from 6105723549

These people have called me three times! How do I get them to stop?

They call every day, say they are from different electricty companies sharing the same internet phone. Yeah, right.

Yes - I got a call last Thursday and just now too - they left a blank 4 sec voicemail and then one saying hello over and over 5 times - he had an accent and there were loud noises in the background... ugh I hope this doesn't become another annoying phone call I have to 'ignore' constantly
