I haven't received a short message from China petrochemical refueling card this month. What should I do?

There may be several situations: first, the mobile phone network or signal problems; Second, the mobile phone number is not registered in the fuel card system; Third, whether the mobile phone is equipped with security software to intercept short messages. If there is nothing unusual in the above situation, you can go to the customer service center to confirm the contact information registered in the fuel card system, and then try to solve it.
