Wedding beach Disaster

Were do i start. Im a single widow of two girls and was happy when 4 years after my husband passed i was able to get a second chance at love. Me and my fiance could not wait to get married. We checked almost 20 locations. And narrowed it down to a wedding venue called california Beachfront Weddings. We met with Rondi and descussed the details and what we would get for our price. We were shocked at the deal we were getting of $4,000 for a beach wedding and light reception. However once we paid our deposit (2,000) all that changed. We never heard another word from her. No emails, no phone calls nothing. We checked on yelp to find reviews and seen one hiden review that was hidden. Of a couple who received a recycled wedding from a couple before them. And shaudy servicr. We spent money on invites, booking other vendors and are stuck with some of them cause we put all our money into it. We are on a very tight budget and saved up just to pay for this wedding. We are now 5,000 in the hole and no venue anymore. Please help. If any company would allow us to get married at there venue plus a light reception of a cake appetizers and champange toast. We didnt want anything big. Just wanted to celebrate or love and have a commitment ceremony for my girls.
