Policy Bazaar — disturbing calls again and again

Why are we getting calls again and again when we clearly said we are not interested?
I submitted a complaint earlier too.
What steps have been taken then?
When we said we are not interested for the nth time on a sunday the executive is shouting on the top of his voice.
His number is - [protected], [protected]
We have no count of the calls which we have been blocking since a week now.
Please take some urgent action and block this number - [protected] or we will be taking some strict action against policy bazaar now
