These people show up at a location I work at, walk me around my property showing me different places that a tower could go up, taking up about 2 hours of my day. Later that day I was sent a proposal, 2 weeks later after speaking with the staff we decided to go through with the idea. After sending an email to set up an official meeting she tells me that they have decided to pursue other places. They will waste your time, 2 hours in person and 4 or 5 emails back and forth only to pull their proposal. Extremely unprofessional, I would not recommend working with this company at all.
