However, as much as I mentioned that to find the new customers’ database is important; there is also one thing that your business should abide as your business motto is make sure that you make your customers both new and old impress with your service in the long term by paying attention to your customers; you must feel that your customers’ problems are your own problem and try to solve the problems as soon as possible when it occurred, or else your new prospective customers and also including your old customers would probably become the new customers of your competitors instead.
