When it comes to freelancing, you always want to make sure that your Buyers come first. The moto "The customer is always right" is one that you must live by. Your clients are the lifeline of your Business, and here on Monster Backlinks, Business is what this marketplace is based on. Therefore, no matter what they say, no matter what they do, you as a seller have to keep your cool, never get angry, never argue, be as mature and responsible as possible. Reason being, battling your customers is not just a battle you can never win, but if you take things to far, you may just lose your account/ be banned. All in all, keep in mind: who has the most to lose? and who needs who in order to be successful?
