Hyatt review: Room reservations

I have reservations for the Grand Hyatt Istanbul from April 8-12, 2020, Confirmation Number: [protected]. I have 2 room reservations, one for myself the other for my 85 year old mother. I understood that when I made the reservations the rate had no refund and cancellation restrictions. I made my reservations in early December and the world was not facing the Pandemic of the Corona Virus. I have been in touch with the hotel representative: GUL BAHAR POLATOZ, asking for an extension for a future date. The representative has been asking me to make reservations by March 15th and to travel before August 2020. At this point there is no way I can make such commitment. I will need to travel to Istanbul in 2020, but it might be in the fall since I need to make sure it is safe to travel. I've never heard of any large corporation not being able to accommodate during health crisis.
