Olx India — Olx India Unwanted Calls from OLX Auto

I’m frequently receiving calls from OLX Auto. I told many times my vehicle is not available and requested them not to call and update the same in their system.
Very unfortunate, everyone says sorry for the inconvenience, and we will update but no action taken, and I was kept on receiving calls.

I regret myself contacting OLX Auto and I have already informed few my close mates not to contact OLX Auto at any situation.
