What would you do if your customer cannot understand you?

If a customer cannot understand me, I would first assess the situation to identify the specific barrier to communication, whether it's language, terminology, or a misunderstanding. I would then simplify my language, use visual aids, or provide examples to clarify my points. Additionally, I would be patient and encourage them to ask questions to ensure they feel comfortable and understood. If necessary, I could also seek assistance from a colleague who may better communicate with the customer.
