Whats to do After not receiveing Adsense pin 3rd time?????

Google Adsense sends a pin code to his every publishers when their earning touches the mark of $10 .Google needs the publishers to enter the pin code mailed to them by standard mail in order to verify the address detail of the publisher.However some times pin code does'nt reaches the publishers of asian countries who belongs to Pakistan , India , China , Bangladesh , Nepal , Srilanka and Bhutan etc
Whenever a publishers reaches the mark of $10 google adsense send a pin code to the mailed address written in the adsense account.After receiveing the pin code publishers have to enter the pin code written in the envelop.If any publisher do not received the pin code 1st time then publishers have 2 more chances of of verifying their account ... But what if he does not receive third time also?
