A callback is a phone call made in return to a customer after they requested it. A сallback is a perfect decision for a prospective customer who has expressed interest in an offered product. A customer can order this service in the case of contacting the business with a complaint or issue (they may want to get a solution or follow-up on a previous interaction). It’s hard to underestimate callback significance because it’s an important aspect of customer service and sales. It allows businesses to provide timely and personalized support to clients and create a positive image of a company.
