I have been using this 'service' for 6 long months. Biggest scam/joke of a company. Sprayer doesn't show up or doesn't even do the job properly. The first two times were good, every other time service was bad. They tell you a time, don't show and the receptionist just believes everything she reads. If there is a quality control officer with the company, they should be fired when the better business bureau investigates this company. Cannot wait to finish this contract. Buyers be ware.
