Customer Testimonial

When I ordered a receiver, I was sent an e-mail after the first three days of no tracking number apologizing for the inconvenience and offering several solutions to the issue at hand. When I replied, my e-mail was answered within ten minutes, telling me that the receiver should arrive that day.
