False advertising in competitions no winners announced re

Good day

I trust you are well I recently entered a competition a month and half ago on my pond hotel the announcement of the winner was suppose to be 5 March which never happened. To entered the competition we had to like share and go on other social media to like their page. To date no winners were announced. When I phoned them to query they false advertising they said they will get back to me untill today never contact and never chose a winner. My concerns are they are false advertising to get more viewers on their page
