When a customer raises a complaint, avoid denying your mistake or trying to explain why the problem occurred. Instead, focus on finding a solution to the issue at hand.

Never respond to a customer's question with "I don't know," "it's not my business," or "nothing can be done." It's crucial to ensure that the customer is satisfied with the outcome of the interaction.

Under no circumstances should you disrespect a customer. For instance, don't call them "incompetent" or "irresponsible" in an attempt to appear knowledgeable. Instead, provide solutions without criticizing the customer.

When interacting with a customer, avoid the following:

• Closing the door in their face and telling them to return in four minutes
• Arguing with a customer or denying responsibility for selling a defective product or service
• Accepting payment from a customer for a faulty product or service
• Imposing rules that inconvenience customers
• Speaking condescendingly to customers
• Making unnecessary calls to inform customers about new products or services

Having an experienced and courteous person handling customer interactions is essential. Failure to do so can result in the loss of significant investments. Therefore, it's crucial to prioritize customer satisfaction and take significant steps to become a customer-oriented business.
