Why do individuals receive bank-enterprise reconciliation binding documents from banks?

The reasons are as follows, according to the query on the official website of Hualv.com.

1. Other customers’ mobile phone numbers were registered incorrectly during the business registration process.

2. Other customers have previously subscribed to the SMS notification service, and later canceled their mobile phone numbers, but did not go to the bank to cancel the SMS notification service. Customers who purchase the number again will receive text messages about account changes that have nothing to do with them.
