Can I refund the broadband fee if I send my mobile phone to China Netcom in Yongnian?
No, you signed the agreement when you applied for broadband. If you unsubscribe, you will violate the agreement. If you unsubscribe, Netcom will not refund your money. If you owe money, he will blacklist you and take legal procedures to recover the arrears. Moreover, paying it will not eliminate your blacklist. You should consider signing carefully in the future.
