Trai — unsolicited phone calls on dnd number

Address:

411004

My name is sneha thakur and i am a resident of pune city. I have been receiving phone calls regarding trading from various companies from past roughly 3 months. I am not sure why and who has provided my number to the trading companies but this is really bothering and affecting me as i get calls at any time on any day - weekends also.
My concern is, if it is a dnd number then ideally this should be reflected in the calling registries and so the callers should take due cognizance of the same.

I have also registered this compliant with vodafone today.
