I did 3 service calls for them and setup an account through their automated invoice/payment system. I submitted my invoices & never got paid. I subsequently had to spend hours & numerous calls to their billing department, just to get paid on 1 of them. I never did receive payment in full & have given up because the time spent trying to collect is greater than the actual work that was done. This is a scam company and you're better off staying far away...unless you like to work for free.
