call block app needed

[wetbar]

Hey I am looking for an app that will block a call when the phone rings more than twice in a minute. I am a landlord and have tenants that will call me 10 times in a minute to tell me the stupidest things. If I move then to the reject list then they can't call ever. I want them to call back just not 10 times in the next minute. I would love to block their call for 10 min or so.

Thanks
