I blocked Unicom's letter business, but Unicom kept sending harassing text messages. What should I do?

Dear, the function of blocking Unicom's letter is only to block Unicom's letter information. Industry ports are no longer blocked, and voice value-added services, such as color ring tones, cannot be blocked. After sending the short message, I just can't receive the short message from the ringtone platform, and I can't send the short message to the ringtone platform, but the voice function of the ringtone is normal. There is also shielding Unicom from affecting the customer's point-to-point SMS function after the service. And you can still send and receive short messages with the following numbers: 10/0, 100 101,96 130, 96130. 106558 1 1, 106558 1868535, 106559 130,10655 I hope I can help you, thank you!
