This question helps to assess and measure your communication skills and the ability to rectify if something goes wrong. Here the interviewer is looking for an answer that shows your problem-solving skills if the first attempt to solve the problem does not go as planned. You can share your story of how you communicated something to the customer, and they miscommunicated, after which they were quite upset. Here’s how to tell the story -  “Once a customer was making a hotel booking, and he called to know if there was any coupon code he could apply to get more discount. Upon checking, I came up with a coupon of up to 40% discount and conveyed the same to the customer. He misunderstood my message and thought it would give him a flat 40% discount. He called again and complained about not getting a 40% discount on the price. I realized that he did not understand it. So, I informed him clearly and thoroughly again.”
