Lady left following message on my Dad's house phone on Thursday March 23, 2017. "Call back at 989-546-6790 and have a copy of your statement with you to review and apply you reduced supply benefit. Your reference number is E009234. Thanks." Looked on on web and found this site. Thanks to everyone.
↪ Earlier today, I received a call and voice mail from 855-206-3606 that gave this number as the callback number. That nature of the message makes it sound like this could be the number for an alternative natural gas supplier even though the caller never gives the name of the company she represents.
