Called my unlisted number that is on the do not call registry. Left no message. They can forget about doing any water testing in my home. If they don't bother to respect the do not call registry, forget about trusting them in anything.
Just got the call, I listened to the whole message, it gave me an option to press #2 to be removed. Hmmmm, even that seems dodgy but I tried it. Let's see if it works. ugh. So sick of all these calls even though I'm on DNC. Such a joke DNC.
