What should I do if I am stopped sending business information, advertisements and text messages?

You betrayed your integrity in a hurry. Once you lose trust, it will be very difficult. In fact, there are many ways to advertise, such as finding a short message platform like Haoyu Information Communication, which is cheaper and safer than mobile phone reimbursement. In this case, I suggest you go directly to the business hall with your ID card, which will give you more opportunities.
