Smeco.  My answering machine recorded automated call asking for someone to press a number if this was the person responsible for the bill.

I got called by this number, telling me I had a past due balance and that I would be disconnected in a week.  I called SMECO and they confirmed my account wasn't overdue. Either the number is being spoofed or SMECO's own billing system is whacked

Received a call from this number today. No message left. Ironically, I do not live in MD and therefore as far as I know, if this is SMECOs number, I'm not a customer.

Just got a call as well and no message left.  Not a SMECO customer either.

Student Debt Relief program scam, automated.
