(512) 596-1965

Got the same in the mail. Didn't bother calling after reading the 1st comment here. :-)
Also looked up the bar code they used - apparently for mailing envelopes.

Received a postcard via USPS, with no company name, stating that they were trying to deliver a package and that this was the final notice. A female voice representing Impact Distribution answered, but hung up after I asked what the card was about and that we had not ordered anything. Called a 2nd time and made it sound as if I was interested in the package. They wanted to deliver a water testing kit and a $25 gift card, also wanted the owner of the house to be present (aha!). The 512 is our area code. Beware!
