Getting calls from a debt collector, but it’s not me

Location: Illinois

For the last month or so I’ve been getting calls from a debt collector looking for someone named DeShaun. But that’s not me. I’ve never been called that, nor do I personally know anyone by that name. I’ve told them repeatedly that it’s a wrong number, but I’m 99% sure that they get that excuse from people dodging collections every day. It’s really starting to get on my nerves though. Is there anything that I can do to get these calls to stop? I’ve had my identity frozen on all credit bureaus so I don’t think anyone can be using my identity to rack up debt. Any advice on what I need to do to get these calls to stop would be appreciated.
