1. Find the relevant order information by shaking the order management function at the back of the store, and see if there is any contact information of buyers or sellers. In some cases, buyers or sellers will actively provide real contact information for further communication.
2. In the process of chatting with the buyer, you can try to ask whether the buyer can provide real contact information. However, please note that this must be based on the buyer's wishes and should respect the buyer's privacy wishes.
3. For merchants, if you really need to communicate with buyers by phone, you can consider using the official contact information provided by the shake shop, such as customer service hotline or online customer service, and apply to the platform for assistance in contacting buyers.
