didn't pick it up.

called several times with different last 2 digits

Likely Rainsoft/Envirotech water treatment.  They do not leave a message, but will keep calling.  Last two digits may be different as they have several lines.  They want to tell you that you "won" something and then come to your house for a "free" water analysis/sales pitch.

Called my cell several times during the month of May and now June.
I never answer due to the comments on this site.  If I decide to pick up, I will report back with the information.

Just got a call from this number.  Just like "anon" said above, they tried to pitch to me a "free" water analysis and give me a "free" vacation.  Nothing is free in this world, so I asked her how they were making money..she responded by reading the same exact thing to me.  It even involved her saying "Have you guys had a chance to settle in?" twice....so she was reading something.  This is a scam I am sure and you would end up paying for the water "treatment".  Call them and tell them to remove you from their list.
