You may a complain to FMB.

For sure, if you surrender now, you'll be getting the surrender value as stipulated in the "table" shown to you during sign up.

Unless you're looking for filing a dispute with HLA and not happy with the surrender value because you have been misrepresented by your friend agent. Thus, you may give a try to lodge your story to FMB and if FMB sides your story, you'll be awarded 50-50 of the settlement (50% for you; 50% for HLA) under neutral verdict. Why not give a try there unless you're not convinced with your own story.
