I am a Unicom card user in Changchun. I want to ask why my customer service phone here can't get through. Does customer service go to work on Sunday today?

100 10 customer service phone is answered 24 hours a day. When I couldn't get through, did you pay attention to their system prompt that you were busy with manual customer service or other prompts? And if you want to check the phone bill of your mobile phone number, it is more convenient for you to log in to the online business hall www. 10 10.com with your mobile phone number and service password. If you have to ask customer service, I suggest you find a free time to call, for example, it is estimated that it will be easier to get through at three or four in the afternoon, and most of their users may concentrate on calling the customer service hotline at noon or at night, which will be relatively difficult to call in.
