Everyone wants to be treated well, especially when investing in a significant renovation or expensive product. Companies who are friendly, knowledgeable, and quick to respond to customers will build a reputation for their service. If you are focused on your customers, they will feel taken care of and that you are helping them meet their needs or solve their problems. Bad customer service will deter repeat customers and referrals. It will likely result in negative feedback and even bad online reviews. If you want your customers to take care of you with more referrals and more business, you need to treat them well.
