Fix links on my website

My site realestateviews.com.au is Wordpress with Avada theme using Fusion Builder and there are 3 contact forms where visitors provide info but this is not working (i.e. info is not forwarded to me)
My PPH developer was paid in full but is no longer contactable so I need someone to do these simple fixes as I cannot do it myself. If you are familiar with Wordpress with Avada theme using Fusion Builder please reply and I expect that it will take very little time
Thanks Robert
