I received a card from this company when I moved in offering a FREE gift. the girl said i do not have to buy anything to get the gift. I let them come out and when they were here they said i had to watch a water test. ok we did. then when we told him we were not buying anything he began using foul language and my husband had to make him leave. It has been 3 months and my gift is still "in the mail". The company is Water Source.
