Unsolicited Spam call

I’m not sure if this belongs here or not. But I got an unsolicited robo call from a “We buy houses” at work. It’s possible that it’s a legit business, but they definitely didn’t give an option for removal, and we’re on the do not call list. I figured if they’re making unsolicited calls, then they probably deserve to get some as well. The message stated to call them back at 317.664.7844.
