Horrible service with no feedback.

What can I say. I booked tickets in Jan 2020 before COVID for Dec 2020. Travelstart then sent me an email stating that the tickets can be used to end of Nov 2022. Since I was unable to get any reply or get hold of them on the telephone. I requested a work colleague to visit them in Cape Town. When he went to their office in Gardens they told him to return the next day since he needed an appointment. He returned the next day and met with a lady called Aviwe. Who told him that I need to send my query to her which I duly did to try and get flight dates. Some consultant sent me 2 dates for travel however since then I was retrenched. I sent Aviwe a total of 3 emails . 28 July,5 August and 11 August 2022 stating that I need a refund. The one reply I received was wait on the refunds department to sort out with the airlines on the amount. Too date there has been no call or email from the refunds department. Is Travelstart waiting to end November 2022 then tell me it's too late and I loose R 23000.00. No way not in my current situation. The airline was paid in full and have collected interest on my money. I called Qatar airways and they referred me back to Travelstart. So is someone from refunds ever going to get back to me or do I have to send someone to your offices in Gardens Cape Town to resolve this impasse.
