Signed up for one month (28 days) service paid up front with credit card. They went by different "internet" name. After 28 days the company that was hired by the company they hired informed me that they had no instructions for taking away the unit after 28 days. Then I started getting AW invoices which I have been getting for up to 3 years after the fact! Called to talk with their office- what a joke! Every invoice was different! Everything from a couple dollars to over a hundred! Total scammers!
