American sounding recording about reducing electric bill. Press zero and talk to a live guy with an accent so heavy and thick I couldn't even identify the accent and could barely understand what he was saying. I knew it was a scam and wanted to mess with him for a while, but he kept asking me to verify my phone number "in case we got disconnected". I told him we weren't going to get disconnected and he should just talk. He disconnected me at that point and I blocked the number.
Multiple calls related to lower electric bills stating notice was in phone bill. No company name or way to get on do not call list. Only option given is to press 0 to be connected to operator.
