Vodafone India — Marketing calls and sms

Address:

New Delhi, Delhi, 110046

My Vodafone number is on Full DND despite that I am on daily basis receiving Marketing calls and SMSs. Marketing People always says that they do not see my number on DND list. I made so many complaints to Vodafone stating that I am receiving these calls, instead of giving me a solution they asked me to provide caller details like number, date, time and content of call or sms. I provided them for continuous 4 months but despite that they are not providing me a solution. I believe Vodafone is just making fool of me and not registering my number on DND and not interested in providing me a permanent solution. Could anyone help me with this and how much claim I can make on Vodafone for getting disturbed atleast 10 times in a day?
