Just had the same phone call. Answered it, there was a long pause, a male thick-accented voice said my name and said he was calling from an electric company about my bill. I do not have an electric bill in my name. I said that who they were calling was unavailable and he hung up on me. Do not give them any information.
Received several calls from this number, didn't answer phone because I didn't recognize this number, they never left a message. The caller I.D. read Indian Head, Maryland. I tried to call this number back several times and got a recorded message from Verizon saying " your call can not be completed as dialed ". I tried to call the number dialing with a 1 first and then again without the 1. This has got to be a scam, maybe the call couldn't be put through because it comes from out of the US and you needed more numbers to dial it direct, really don't know, just a guess on my part. Anyway, BEWARE, don't fall for this scheme, don't give out any information. Stay safe, be smart.
