Policy Bazaar — Irritating calls

I installed policy bazar application to check some information. I never agreed for any calls from anyone from policy bazar, after which I kept on receiving repeated calls from different landline numbers sometimes 3-4 times a day. I am not able to block these numbers because all of them are different numbers. I want to make a complaint about these repeated unnecessary calls I am receiving several times in a day. I spoke to the person and clearly told him that I am no longer interested in your service, I even uninstalled the app to avoid these calls. Still, I am getting the calls daily. This is extremely annoying. Please report this to policy bazar and stop this nuisance immediately
