Flight Center Port Elizabeth & Ethiopian Airlines empty promises

I booked flights through flight center Port Elizabeth, my consultant, Angelique Fondling assisted me last year, assured me I can get a full refund for my flights, had to cancel the flights. The processing took a good few months, I have now heard from her Ethiopian Airlines are now refusing to give me any refund as the original tickets were non refundable. In the begining before purchasing my tickets I asked Angelique if this would be refundable and she said yes. What ******* service and customer care, there was suppose to be a covid 19 policy that allows full refunds. What do I do next? Alot of money has now been lost which I actually need. Anyone got any advise?
