I didn't buy anything. I received a parcel from the postal service.

Without buying anything, receiving a parcel may be the following situations:

1. Shopkeeper's brushing behavior: Shopkeepers use your personal information to brush a bill without buying anything, thus simulating the real transaction process and improving the ranking or credibility of the store. In this case, the package may be empty or contain products that you did not buy.

2. Misdelivery or fraud: The merchant may send you the wrong courier information due to operational errors or intentional fraud, or use the courier information for fraud. In this case, the packaging may be the wrong product, or it doesn't match the product you actually bought.

3. Products bought before: It may be that the goods bought before have arrived, but the courier company failed to deliver the goods in time, and now it has been reissued.

If you receive this product that you didn't buy yourself, it is recommended to contact the sender first to ask about the specific situation. If it is confirmed that this is not the case, you can also report the situation to the courier company in time and keep relevant evidence, such as courier bills and photos, so as to handle disputes.
