I went to their office to pay after the installation and I was told that I cannot pay because the invoice is not ready (I have them in my hands) and that they will call me to pay with credit card. After waiting for their call I called them to pay without success. After several tries I gave up. 5 months later I received a call from the owner of the company (very arrogant by the way) saying that he had interest on the bill.

DO NOT DO BUSINESS WITH THIS COMPANY OF THIEVES
