Currently I'm working on Facebook for both content and advertising. That's really a useful channel for both branding and selling products. Beside FB, I'm also running Instagram ads (that is connected with FB ads). They help me alot.

Did you try Facebook Ads type called "Lead Generation"? If not then I think you may need it. Try to re-targeting your audiences, review the ads content or just adjust the budget you spend on each ads set. IMO
