KLM and Travelstart - Clueless and Confused

Flight were booked in June 2019 through Travelstart abroad KLM from OR Thambo to Newcastle (GBR) via Amsterdam to depart Johannesburg 14 April. These flights were then updated by KLM in November 2019. Given the current Cororna pandemic, flights have been cancelled around the globe. The KLM policy allows for flights to be reschedied until end November 2020.

I have attempted on at least 10-15 occasion to try and resolve this issue with both parties with absolutely no closure. KLM keeps on sending me back to Travelstart stating that the tickets are still under their control. Travelstart sends me to KLM stating that the tickets have been handed over to KLM. No party is willing to take ownership of the situation and attempt to resolve the situation and I do not have the leverage so resolve this myself. These two parties are both reliant on each other to both operate and provide a strive to end users yet when the need to resolve a mater arises they both seem to want to distant themselves. All I want is for our vouchers for our flights to be provided to we can book at a later time.
