Disgrace with Kulula and Travelstart service

Aletta Yvonne Stander. I habe been using Travelstar for few years booking flight tickets. With COVID-19 I have been sending emails requesting a travel voucher from Cape Town to Gauteng and back. I have paid NO RESPONSE.....THEY ARE A BUNCH OF BULL****TERS. I have tried to phone Kulula as I choose them because of the price inclusive of 20 kg lagguage and hand lagguage. Is this how you treat people whay a disgrace. I want a answer KULULA NOR TRAVELSTAR ANSWER THEIR PHONES OR SEND RESPONSE. phone me ***. ***
