Kulula and Comair absolutely useless.

Kulula gave us TravelBank Credits for the flights that were cancelled during Lockdown in May 2020. Now want to book on BA Comair, but there is no way to apply these credits to these flights. Have tried calling them, but it's been more than an hour and I'm still waiting. Meanwhile the flight prices rise by the minute. They have basically ****** our money. The least they could do is extend the 'Use By" date by another year at least. But their inability to man their phones is beyond atrocious. And so just when I got through to an operator my airtime ran out. Fly Safair in future. I would like them to know about this review, but they so conveniently don't give an email address anywhere!!!
