[Resolved]  HDFC Bank — asked to remove a number still receiving calls on that number

I had asked hdfc to remove a vodafone number and they had assured me that they have removed it but they have again started calling on that number. Please ask them to don't use that number for anything no call and msgs. This number belongs to my granny and they keep harassing her even though I have provided them with my own two numbers. Sometimes I am not able to pick up calls due to work but that doesn't mean they can harass my grandma and after they assured me that they have removed this number from the account.
