Poor refund process from Travelstart

I have had such a protracted and frustrating experience with Travelstart. In February 2020 I bought a ticket to Paris for June that year, before the pandemic. I was not able to use this ticket in 2020 due to travel bans. In 2021 I app**** to get a voucher for this ticket, which was applicable til 31 December 2021. In December I realized I wouldnt be able to use this ticket and I started the process of applying for a refund, but due to the bad service of travel start, this process is still unresolved. I have contacted travelstart via email and their whatsapp line over 20 times, for over FOUR months and they still cannot tell me if I will get a refund. Currently I am wondering if they have just taken my R9000? It is unacceptable that I have to message them so many times to get a response.
