 Customer feedback

I am very pleased with the customer service provided by HVPD. We have requested HVPD to travel to our site on very short notice, while the service order was still being finalized. HVPD were able to accommodate our request to be on site to meet our schedule, without a hitch. Thank you for your excellent customer support.
