Someone at Home Depot took my number and call incessitantly trying to pitch the water system.  
They call when I'm at work.  They call when I'm at home working my part-time job.  I'm telling them to quit calling me already.  Geeze, I'll never give out my number to anyone I even think may be a solicitor for any free prize of any kind.

I filled out a survey at Home Depot about water systems.  These calls are my punishment.

Same here ! The only thing the girl at Home Depot said was that it qualified me for gift card --no mention of a solicitation.  And everyday calling at that !

I have been called by this number and also 972.647.4700 both without messages left.  Searching 9726474700 finds a walter filtration company.  I now remember answering some questions for a survey for a water filtration company at Home Depot a few weeks back and suspect these are sales calls.

I've had occasional calls from this number, as well, with no message left over the last 3 or 4 weeks.  Any info?
