Pressed 5 as recorded message instructed only after receiving numerous calls from this number. Probed to find out who call was from, company name, what company does, etc. Person I spoke to denied it was a telemarketing company but stated that they represented "numerous" gas suppliers and their purpose was to advise people on what gas discounts they qualify for as a result of "recent" deregulation. When I told her to remove my number from their calling list, she hung up. Come up on caller ID "Westlake, OH"
