Competence and attitude are the key for customer service
I have used many hosting services. Softsys Hosting stands out among them. They are not a big company, but they offer reliable and cost-competivve service, and more importantly, a great customer service. Unlike some big companies, they do not offer phone support generally. This may make some apprehensive. I have found their technical support via email is more responsive and efficient that phone support. For urgent requests, they respond in minutes and often solve the problem instantly.
The key to their excellence is competence and attitude.
