There are a few tips and tricks that you must keep in mind while dealing with difficult clients.
First of all, always ensure that you are properly listening to everything that your client is telling you. In no way should you argue or talk over your customer, even if you know that they are mistaken. It is always better to let them finish first and then politely explain things to them.
It is also very important that you establish a bond with the customer and try to empathise with them. You should imagine yourself in their situation and show them that you understand their situation and perspective.
You must always remain calm and composed and handle the situation in a very relaxed manner. You should set a very polite tone for the conversation and maintain a low pitch in your voice. Even if the client raises his voice, you should continue the conversation in the same calm manner and you will observe that the client too starts conversing with you in a decent manner.
Whenever the client argues with you, do not take any of his abuses or harsh words personally. You should not get affected by their frustrated behaviour since it is how they are and you are not responsible for that. You must stick to your job and explain to them the required steps and directions for future processes. Do your job effectively, ignoring any external expressions or factors.
Do the tasks that you have promised to do on time and in the most efficient way. You don't want to give the client any chance to complain. Sometimes certain clients are a waste of time and effort. They will trouble you for a long period but still not buy your product or service. In such conditions, it is essential that you recognise these people and step out of that dynamic.
