Your unique identifier should give you credit for the sale. However, I am not sure how to verify that since if you don't know they have visited your site and gone ahead and applied without calling you how would you even know to check?
We had that happen once (only once as far as I know, with C1, not H1). The only reason we knew they applied was because they called us for status. Never got an explanation as to why were weren't credited. Just an "oops" sorry.
On the Medicare side, we have a sneaking suspicion H calls our clients at open enrollment and tries to switch them to something else, then take client from us. It has happened at least three times that I know of. The reason we knew was because the client got suspicious and called us to see wtf the company was trying to pull. It pays to keep in touch with your book. Especially the seniors. If you can get htem to trust you, all is good, because most of them sure don't trust the insurance company (and the govt).
Thanks for the info - you just saved me some pain.
