Refund outstanding for nearly 6 months - Consumer Complaint for AVIS RENT A CAR - HEAD OFFICE

Paid for a rental booking in Feb 2020 - in full - in advance for rental in July 2020 (3301-8906-ZA-4 PP). Booking was changed due to Covid to Nov 2020 (paid more money to make this happen). Then cancelled booking due to covid. Was assured i would receive a refund. Contacted AVIS 7 times to date, without a single cent refund. This is rediculous if not theft. WHERE IS MY REFUND?
