Piece of advice, @GoodMemoriesDMD.
By now, it's best to rethink how the staff within your company handle public interactions. This has been a recurring issue for years, and it needs to be addressed.
When makeup artists and other team members publicly argue with fan feedback, it severely damages the brand's credibility. Every employee is a representative of your company. Enforcing basic professionalism is a must because, right now, their behavior is reflecting poorly on the entire organization.
