BAD SERVICE. I WANT MY MONEY OR TICKETS

In December 2019 I booked for a 7 night stay in Mauritius for 4 people. Which is my wife and 2 kids and myself. When Covid19 struck, we couldn't travel anymore. Since from 2020, we spoke to the Customer service manager, at Travelcheck by the name of Lisa. She advised us that as soon as the flights become available she will let us know. It has been almost a year after Covid19 and I am still waiting. I have sent her multiple emails and she then told us that Travelcheck will refund us because they do not have available flights anymore. We where then assisted by Marcia Makukule, regarding the matter but we still do not have our refund back. It is either we get our money back or our trip must be back in motion.
