Travolook — Refuse to refund

My name is chasa collin kapele, i booked a flight on 15th July 2022 and it was canceled by them. I was told to wait for my refund in 7-10 working days. Today is 10th September 2022, it has been more than a month of calling them and each time they tell me in two days i’ll be refunded but i haven’t received my money. It is only in my rights that i file a complain to higher authorities.
