TRAVELSTART

i Booked and paid for an Airline ticket via Travelstart with Emerites Airline Due to Covid 19 I cannot travel. I even paid extra fro my seating. I want a refund and the Airline is saying they are deducting for all sorts of things. I want a full fare refund including all the extras I paid for . MY TICKET REF IS TB***0 I have tried changing my dates which they intially accepted , but now I still wont be able to travel . Where is the fareness in Airlines putting off so many Staff and I cdont get a cent back a full refund I paid like 6 months in Advance.
