Any company that is hoping to get to a point where it can help people in a lot of ways that are going to be improve their lives should focus on things like customer service. Some companies think that if they provide a really high end product like tree service then customer support is not going to be something that they really need to think about all that much once all has been said and is now out of the way. The reason behind this is that they have become used to having monopolies in these industries, but these monopolies are starting to break and this has made customer service even more essential than might have been the case otherwise.
You should factor customer service into your own decision making process. Always hire a friendly tree service provider rather than someone that has an attitude. Remember, you are the person that is paying them for the job that they are going to do, which means that you are their employer. If the tree service provider is acting like they are doing you some kind of a favor then they might not do a good enough job anyway so you should look for someone else.
Good customer service is a sign that a business cares about its customers. You are paying your hard earned money to them after all, which means that they have a responsibility to not just do the job that you have asked them to do but to also treat you with some modicum of respect. You should be respected as a fellow human being if nothing else, although some might argue that customers deserve even more respect than that.
