How to close assistant wo's business?

When I inquired about Unicom's package service, I saw Wo Assistant in the package. I want to turn off this function. The refund method of Unicom Wo Assistant service function is as follows:

Tools/materials: Xiaomi 12, MIUI 13, Unicom V9,0, 1.

1. Open the China Unicom app and click the customer service icon.

2. After selecting customer service, contact customer service to unsubscribe.

There are three different services under the service of Assistant Wo: 1. Missing letter reminder: free of charge. If someone calls you but you can't get through, assistant Wo will send a text message to remind you of the calling number and time. You can also receive reminders by following WeChat official account. The calling party does not charge the call fee.

2. Voice message: The voice message function (about 20 seconds) is added on the basis of the missed message reminder, so that the called party can listen to the message for free through WeChat official account and the link in the short message. Judging from the tone of the message "DuDu", the caller charges a normal call fee-you can use the free resources of the package.

3. Intelligent answering: On the basis of voice message, add AI assistant to answer for you, guide the caller to have a simple conversation and understand the caller's calling purpose. The called party can listen to the conversation for free through WeChat official account and the link in the short message. The calling party charges the normal call fee and can use the free resources of the package.
