I returned the call and heard a recorded message which stated, "Today, you were contacted by EcoSolar."

I received a call from this number and I couldn’t help but notice it's posing as a solar energy firm. Interestingly, I've had a similar call lately, although the last two digits were slightly different. It’s rather peculiar, don’t you think?
