The service was scheduled ONE TIME and an agreed to price was established. They came out several more times (without my knowing) and then started charging me for "services". I cancelled the service and it took months to get a refund of some of the money they charged my card. This was two years ago. They just left a message on my phone stating that I was a "current customer" and they'd be out to my home for servicing. I called and told them that if their van rolled up in front of the house, I would call the police. This is a VERY sneaky company...yes, a SCAM!
