How would you handle a client who was given a poor service and comes back complaing bitterly to you?

1. Start with kindness and empathy ,sometimes just a smile and asking nicely will get you what you seek. 

2. Come prepared walk up to the counter, have the date of the incident, order number, product ID, receipt, account number, and payment info handy and ready to present.

3. Use an authoritative voice and speak with confidence when building your case and lower the register of your voice if you can. 

4. Be assertive, not violent and don’t put yourself in a worse position by throwing things or threatening to set the building on fire . Most businesses are willing to come to a resolution with clients if they state their case well and stay firm.

5. Take the business elsewhere and don’t put up with crappy service, especially if it becomes a frequent problem.

Always use your initiative when dealing with complaints.5. However, never pass the customer around from person to person.6. Once the customer has aired their grievance, you should immediately give a sincere apology. 7. Customers never want to hear excuses.
