Struggling to get the refundable deposit I paid back

I'm still waiting for my deposit after attending an auction that took place from the 8/8/19 to 10/8/19. When I call in I'm always told they I'll get my deposit the day I called but I feel like I'm being taken for a ride. Please be careful when attending auctions, make sure you pay your deposit using cash so that you can get your money back inmmediately once the auction is over whereas if you do an electronic payment you have to wait to recieve your deposit which might not even come.
