Answer: The important thing is to listen and try to offer solutions.
Explanation: The client who shows concern is looking for results, for solutions, and that is what you have to offer. In my case, when a client communicates his concern to me, I first let him express himself and let him know what causes him concern. After the client has expressed his concern, my focus is on finding a solution. I analyze all the aspects and try to finalize the attention to my client with ideas to work the problem.
