Booking flights on TravelStart

I can only confirm the poor experience that others reported. Communication with TravelStart is like trying to communicate with a stellar Black Hole. Nothing comes back. I had to cancel a return booking. It seems they will penalize me with the basically the 90% of the total booking cost with the warning that it will take up to 5 months get any money back BECAUSE of the "current situation" After the cancellation on their mobile App on the Friday midday before the outward Monday morning flight, I also sent an email for the "more": help that I apparently needed according to the App, but only got an email response back the next Wednesday with info what I should have done but for cancellation 24 hours before the Monday flight. I have not been able to raise anybody on a phone call.
