RIP OFF!!! I have been a customer for 11 years. 2 Years ago my equipment broke. They replaced the piece of equipment, and told me it was free, but I needed to sign a work order saying they were there. THEY LIED TO ME - IT WAS A 5 YEAR CONTRACT that I signed - and now telling me there is no way out of it. They are liars and do business through deceit!!! DO NOT USE GUARDIAN!!!!
