Bharat Matrimony — Repeated calls

I get atleast a lot calls from Bharat Matrimony. I have repeatedly requested them to remove my number from their Database, but they ignore my requests and call me on my mobile everyday. I request the concerend authorities to take action and ask them to stop this nonsense at once.
I just want the calls from Bharat Matrimony to stop.I can be contacted at [protected]@gmail.com to get my mobile number.
