1. According to the inquiry of Youngor Group in official website, collect evidence: First, collect as much evidence as possible, including but not limited to conversation record, receipts, photos or videos with waiters, which will help to better explain the problem and increase the possibility of obtaining compensation or solving the problem.
2. Communicate with the store manager or manager: You can try to communicate directly with the store manager or manager to explain your dissatisfaction with the waiter's attitude and ask for measures to solve the problem. Direct communication with senior management can solve problems faster.
3. Complaints by telephone or online channels: You can call Youngor customer service hotline or make complaints through online channels such as official website. When making a complaint, it is necessary to provide detailed complaint contents and evidence so that customer service personnel can better understand the problem and take corresponding measures.
