Prompt, courteous, knowledgeable service. Following my call, I got a call back in under 20 minutes. The person who responded was familiar with the system. We agreed that he should come to the house to check out the system, which he did the next day. By that time the system was working. He felt we should leave well enough alone. However if I do have to replace the system in the future, I will definitely ask Startec to present a bid.
