Used zFast for a few years now, never ever had a serious issue with their customer service. The services they provide are extremely beneficial and low priced for their quality. They provide customers with information, even if it doesn't link in with what information they can give. I would recommend zFast to anyone and everyone, purely because they are the best company i've ever dealt with. 5 Star Service, 5 Star Products & 5 Star Pricing.
