I got three calls in a row, all phone numbers with just one digit different. The first was from Member Services, 312 340-5580, the second from Customer Servic, 312 340-5582 and the last from Electric Bill 312 340-5583.
been calling me past few weeks from different numbers: 3123405583, 3123405580, 3123405585, 3123405582, I just put them on block list, have not answered. though, by mistake called one back and recording said to dial 1 for removal from calling list. I hung up as that is a scam and it never removes you for their list.
