MagicBricks — Shared my personal phone number without my consent to the agents/builders

Address:

Crossings Republik Ghaziabad

I was searching for a property on magic bricks and regarding that i got a call from their represetative i gave him all the details of the property i was looking for...later he asked me that can he share my number with the agents and i very catagorically told him not do so...instead i told him to send me the property details and i myself will contact the ones i would be interested in...despite my saying no he shared my details with n number of people and since then i am getting calls and WhatsApp messages through out the day claimng that i have shown interest in their property...which is not the case...
How can Magic bricks share my personal phone number without out my consent to anyone its the breach of my privacy and they should be held resposible for that...
