Who called from 2199612357

This call was someone trying to sell me on going with a gas supplier other than NIPSCO. They claimed they could save me money by supplying their gas to NIPSCO for me, but he couldn't tell me how adding another company, a middle man if you will, would save me money. They've called several times, and the numbers are spoofed.

Call came in on LANDLINE - Callers name is UNAVAILABLE.  They left no message and I don't return unrecognized numbers. Scam call.

Just like the previous person, this number claims that they are with NIPSCO. I immediately hung-up.  The caller ID number did not identify NIPSCO but the above number.  A scam.

No msg, when I saw unavailable I tore into them then said what, and nobody there
