I have handled the obligation to terminate the agreement in the business hall. Why does a mobile phone number send a text message saying that I owe money, and still send such information frequently?

According to the information you provided, if you are referring to the business of keeping downtime in the business hall, you usually need to deduct the cost of keeping downtime during the period of keeping downtime. If there is arrears, it will enter the state of arrears downtime, and the system will automatically cancel the account after the arrears downtime exceeds 3 months. It is recommended that you contact the local Unicom manual customer service for verification and follow the instructions. The specific situation is subject to local policies.
