Travelstart. TERRIBLE POOR POOR SERVICE. NO HELP IN OVER A MONTH

Since 1 December 2021 we are trying to move a booking that was affected by the borders being closed due to the new Covid variant. Travelstart was contacted on all platforms but they refuse to assist. Even on new bookings they don't come back to us. We have tried all means of getting hold of them but it seems they took our money and closed shop. I cant even log into my account as there server seems to be off line since the travel ban took effect.
