More special than other banks, they must have a home phone number. Even if no one answers the phone, they must have the phone number of a company you just found, because in that case, if they call and find it is not a home phone number, they will directly refuse to give it to you. If the phone number doesn't work, it won't work.
There may be other reasons for your rejection, such as your first application.
bank of communications
Because you don't have a home phone number when you verify the information, and they refused, and your second, third and subsequent applications are not more than half a year from the first application, then your application will also be rejected directly.
You don't want to apply for Bank of Communications now.
