It probably is her number but she did not call you. These scammers fake the caller i.d. info. Never call the number back or press any buttons on these calls. Just hang up, it is a nasty scam. Never give ANY INFO. not even the time of day.
I had a rounds of calls last month about lowering my electric bills with alternative energy. Now it seems to be another round with Green Energy. I put every call on DNC List, but might as well put it on my toilet paper roll in the bathroom - obviously our FCC does give a flying f*** about tax payers being harassed on the daily basis!!!
