Bharat Matrimony — Spamming my inbox even after unsubscribing from the emails.

I have clicked to Unsubscribe dozen times but keep getting emails from them. I have informed them that the unsubscribe link does not work.Even sent them email related to it. They are aware of the issue and are doing anything. This leads to 6-10 emails per day from them. There should be laws about using fake unsubscribe links. I need consumer complaints of India to research/investigate why
