Well, had you taken the time to read a little further down, you would have found out that this is a scam to get someone in your house to sell you a water treatment system that you probably don't need and that will most certainly be way overpriced. Also, they now have your phone number as well.
Did not get a call - instead received a Postcard with this phone number, saying they have been trying to deliver a package and I should call to reschedule. Don't believe it - sounds sketchy. Another site lists the number as belonging to Irving Kucha in Pleasantville NJ.
No call: received a post card today from DMC services asking me to call to schedule a delivery. Seems shady. I called and was on hold for 30 seconds at an answering machine playing music and thanking me for my patience. Than I hung up.
Received postcard asking me to schedule delivery. I called the number, was put on hold. Threw out the postcard. I'm sure it's a scam, just not sure what their angle is
