Because of Ryanair Flight Cancellations, I Lost Money

My flight from Palermo to Pisa on October 20, 2023 (NFWWVı, FR2655) was canceled less than 24 hours before takeoff. I received a notification via email. On the same day, I had a flight with Ryanair from Pisa to Kos (DKIzyt, FR8886). The email stated the opportunity to choose a different flight in place of the canceled one. I tried multiple times through the app to change the application for the flight from Catania to Pisa on the same day. It was impossible, and the only other option was to change this flight with the airport staff, as mentioned. So, I woke up early at 5:00 a.m. and went to Catania. The airport staff informed me that they didn't have the authority to make changes at Palermo airport and couldn't do anything. The canceled flight and the connecting flight with Ryanair became impossible. While searching for an alternative way back to Turkey, I flew with Air Serbia from Catania to Belgrade and then, two days later, had the opportunity to fly with Pegasus Airlines from Belgrade to Bodrum. Due to the flight cancellation, I incurred additional expenses for accommodation, extra transportation, and meals. The extra expenses are not the main concern, but I'm seeking reimbursement for the flight bills paid for my return. However, my requests sent via email have not been received. I couldn't convey my issue through the website or the app. I am requesting reimbursement for the extra expenses I've specified below. I'm unable even to get a refund for the canceled flight cost.

Extra Expenses:
Catania – Belgrade with Air Serbia: 3,349 Turkish Liras / 29.70 = 112.76 Euro
Belgrade - Bodrum with Pegasus Air: 8,283 Turkish Liras / 29.70 = 278.88 Euro
Total: 391.64 Euro
