Hello, I'm social security from Shenzhen. I applied for the fee on August 26th. Why haven't I deducted the fee on September 26th? What to do?

Because the payment period of social security is: August 20th to September 19 as social security in September, and the fee will be deducted from September 20th to the end of the month. Your company stopped for you on 26th, and your social security in September has been paid successfully. September will definitely show non-stop, and you should show suspension of payment next month. But social security found that you didn't stop insurance, and it is possible that your company will stop insurance. However, because it was the deduction period at that time, it could not take effect immediately, and the company needed to make a "confirmation" to stop your insurance, so as to show that you were in a broken state.
