please help me, i emailed to every huawei email for bootloader unlock code no reply

1 month emailing to mobile@huawei.com and to other emails but no reply i sent all information about the phone but no reply:(

Can't reply back to a text or email

Everytime I go to reply back to a text I received it says unable to send message. Sometimes out of the blue I can, but i can't almost all of the time. Or it will say call not aloud. Just didn't know if I was doing something wrong?????
