Expedia.com Stealing from customers

Expedia is refusing to give refunds of cancelled trips. They give customers travel credits then come back saying these credits expired or they make it impossible to redeem the credit. Also hiking fares to make customers pay more money or lose whatever credit they have. They keep saying its airlines policies but the airlines have nothing to do with this. Expedia is taking advantage that many people had to cancelled their flights because of covid. Now they are just robbing us. 

i cancelled my flight on June 6th, 2020 because of covid. Expedia gave me a travel credit that now they are telling me expired in January. If people were unable to travel how could I possibly used my credit before January. So they are keeping my money.
