This company uses a third party company to answer your telephone calls and they are there simply to make appointments to send technicians to your home and charge you close to $100 for this service call . They refuse to answer and have no ability to answer the simplest question you might have . You may not need to pay all this money for a service call just to get a question answered if your equipment is working. I recommend hanging up and calling a company that doesnt use third party answering services but has someone trained available to answer any questions you may have and is happy to do that and stay away from this company and other companies who are just greedy and not willing to answer questions that can be answered over phone that could save you a lot of money for a service call.
