I have registered my number for Do Not Disturb since 2008. Inspite of several complaints, i still continue to get the marketing calls for credit cards, personal loans etc. Every company has a different database which is never updated with the numbers which are registered for DND. Its irritating telling each caller that this number is registered for DND. Can TRAI or any authority circulate the list of numbers registered to DND to all these tele marketing callers?
