Duplicated billing

On April 5th, 2023, I was debited an amount which I had already paid for via Booking.com (Confirmation: ***) prior to the pickup & on Dec 29th, on pick up, the balance was paid by card machine. I have been trying to contact Woodford and my attempts to get a refund have been unsuccessful. I contacted them on April 20th and have not received an email regarding my query as promised. My Whatsapp messages are ignored and when calling the call centre the operator directs me to a line that sends me to a voicemailbox which is full. I have also tried to send an email using their website and it is unfunctional. I am utterly disappointed at their unavailability and surprise deductions 4 months AFTER my rental has taken place. I need my money back as soon as possible as I have paid for everything in advance!
