Not Taking the Bait
One of the simplest techniques you can implement when an angry customer is giving a series insults, comments or other disrespectful comment to you is not responding at all.
Typically, it is not a good idea to directly address customer complaints. The goal in this situation should be to empathize rather than argue with the customer. This method will save you more time because you won’t need to reiterate your argument or talk about the comments further.
One tactic to avoid conflict with difficult customers is not taking the bait. This tactic may be challenging but will keep you from getting upset or forgetting what’s important in your day.
