Dnt want to give voucher

So I booked flights for a company function and now the whole company including myself has COVID or is isolating and obviously I cannot go anymore. I cannot change my booking as at this stage I was going for something specific and I dnt have anywhere else at this stage where I want to go to. Your call Centre refuses to give me a voucher for the value so when I’m ready to fly or have some place to be I can go !!! Why all this nonsense???? Why can you not help a person out and be a bit reasonable!!!! Things are different now and you have to change and adapt your policies too and the way bookings work !!! Things can change at the last minute then you dnt want to help a person out!!!! I’m not asking for a refund I’m asking you too keep the value of money I paid to you, till I know I can travel and where I want to go ! Is that too much to ask!!!!!
