What is a good way to improve customer relation from an adverse situation (context: digital transformation in heavy industries/manufacturing)?

There are many good ways of delivering great service but you start from the basics: Smile, Warm Welcome, Use customer name, Be helpful & Honest. The services and products you are offering should be according to customer needs and wants and not in accordance to your willingness, you should find out what would be perfect for them. You should make him/her feel that they are very important and special customers for your company. Everybody likes attention, even one message is enough to make somebody feel better.
