I have found that the absolute best way to handle this is to make sure the customers are good customers before you acquire them. Here are some tips: 1) Charge for your services. If you don't charge, you get people who undervalue your work and treat you like you are their servants and will whip you every chance they get. Don't work for free. 2) Treat customers with respect. Try to understand why they are upset or angry or not being a good customer. If you empathize, you'll probably find that you have behaved like they are with some other company or service provider. Why were you acting that way? What could have pulled you out of it? 3) Under promise and over deliver. If you don't deliver, they feel cheated, misled, and abused. If you say you will do something, do it. If you don't, you're a liar and people don't like liars. They will treat you bad out of spite. When you over deliver, customers are shocked and amazed and will sing your praises to the world! 4) Take a break. If you are getting abused, simply stop responding to the person for a week or two. Let them contact you again in a nicer tone. When you let them sit on their bad behavior without responding, they usually try another approach.
