Vantage Deluxe World Travel / Vantage Travel Service review: Unresponsive to refund request

I am customer # 7783653. We booked a trip in 2020 in March to visit Holland. Vantage cancelled the trip and promised a full refund which we have not received. I have called multiple times and have received cordial attention, all promising a refund. But there has been none. Today, I called and was told my funds had been placed in a future trip category. I never was notified and never asked for anything other than a full refund. There are records of my calls and some of it has been recorded. Some "executive committee" is said to exist, but I am not allowed to speak to anyone on this committee and customer service cannot name them.
