How will the company respond if things go wrong? It’s easy to overlook this factor when comparing deals from different suppliers, but you should give it some consideration. If your Internet connection stops working, how quickly will you be able to get through to someone who can resolve the problem for you? This is where word of mouth can really help - either from people you know or through reviews in magazines or online. If a company’s reputation is made up of horror stories about hours spent on hold, or engineers not turning up to install equipment, you may decide to take your money elsewhere.
