Over the last one month i have received innumerous calls from HDFC Bank despite having my number on Do not disturb registry. Till now i have repeated told them that my number is on DND and requested them not to call and update their database. However, the calls have not stopped. The last number from which i have received a call is 022-67430162 (today i got a missed call which i returned as it was an unknown number). My mobile number is 9769009225 which i have again checked and is listed as a DND number on http://ndncregistry.gov.in
