I would like to nominate Sofitel Darling Harbour Sydney with a

for not allowing me to cancel or move my non refundable booking for May.
I am a big fan of Accor and i am extremely disappointed over this inflexibility. After this virus crisis is over, i am going to book most of my stays with Hilton, Marriott or IHG .
By the way, has anyone tried disputing a non refundable booking with their credit card company ?
