If the credit card customer service phone of Agricultural Bank of China is not connected, it means that when you call the customer service phone, many other credit card customers of the bank also call this number at this time, and the customer service line is busy. I suggest you continue dialing at another time. If you still can't get through, keep dialing until the result is squeezed into the line. Once dialed, you can choose to transfer to the manual service, ask him/her if the credit card has been sent, and if so, provide you with the mailing list number for you to check the progress.
