This is a SCAM.  The telemarketer leads you to believe they are calling on behalf of BGE to guarentee you are receiving the lowest rate.  What they are really doing is switching you to their gas/electric service...I requested my number be taken from their call data base, he hung up immediately.

443 715 7115 just called and ID'd as wireless caller.   After I picked up, silence.
Thanks for the other responses to know that this seems to happen to many others.

Caller ID said "Wireless Caller" with this phone number.  I answered the call but no response from caller.

Ditto.  Except the actual phone number did actually display on my CID.  Didn't answer, but when I called the number back, it was about saving on my monthly gas & electric bill.  Probably a scam of some sort.

Received this call with a disguised number/ Id. " 64:$C :/../22" without quotes and I was able to ascertain hidden # from call blocker gadget. I called back since there wasn't any info on the # here, and a recorded voice mentioned that "They can save hundreds on my gas & electric bills if I sign up..................At this I hung up!
