Refunding struggle with Travelstart

My wife booked a ticket with CEM Air through Travelstart for a flight on Saterday December 15, 2018 to George. The airline has been grounded on December 14, and the flight cancelled. We have been struggling with Travelstart for our refunding for four months now, although the Airline has confirmed their reinstatement (See mail below) We are struggling to communicate with Travelstart and only get vague answers of Court cases between CEm Air and SAAO. Why can Travelstart not refund us? ------------------------------------------------------------------------------------------------ SUBJECT: RE: REF001 QUE Hi All, The below email is being send. TIME TO TAKE BACK OUR AIRLINE!!!! DEAR VALUED CUSTOMER Booking Reference On Tuesday 18 December, CemAir won an urgent High Court order against the Civil Aviation Authority, enabling us to reinstate our flights. CemAir is an independent airline that takes pride in upholding the highest safety standards and we ensure that we comply with the CAA safety requirements, which is reflected in this High Court decision. We realise that this has been an extremely stressful time for you and your fellow travellers. Again we apologise of the inconvenience caused. We are back in the skies ON ALL ROUTES from Thursday, 20 December 2018.
