I need to remove dummy survey responses (those I created during evaluation period), and invalid ones - responses received from Cancelled tickets - which is a custom status we use to close spam, duplicate, or internal emails. I cannot find anywhere to remove them, and one of your chat agents suggested to remove the response provider (contact). 

I'm not inclined to do what was suggested as there could be valid responses from that contact, so kindly provide another option. And I did try that too for the dummy contacts, but the responses are still there. Please advise.

Thank you.
