The train has left Evita se Perron

We had booked and paid for tickets for a show in April 2020. Due Covid-19, the show was cancelled. We have tried to contact Evita se Perron to enquire as to the current situation in respect of seeing the show or a refund, etc. Unfortunately, no-one in that establishment can, when you do finally make contact, can give you an answer. PD Uys has sold the theatre and we have come to an absolute dead end. We have been told no show until a vaccine exists (that can be a good many years) hence we have decided to request a refund. This has not been forthcoming either. We are at the end of our tether as no-one will/can assist us. We have all correspondence to support and prove the above.
