Regarding non-receipt of refund from Travel Triangle

I would like to inform you that we have booked mauritius trip from travel triangle on 20th feb for 7th april to 11th april but due to covid 19 I have cancelled the trip in march last week that time travel triangle confirmed to us on mail that you will get your refund within 10 to15 days but after some time they said you will get your refund within 40-50 day still we have not received any refund and they are asking for credit note for future travel but we don’t want to go anywhere in pandemic situation. kindly help me out to get my refund .
