SunExpress Canceled My Manchester-Izmir Flight on Short Notice, Causing Significant Financial Loss

My Manchester to Izmir flight with SunExpress on September 5th was canceled on August 15th, less than 20 days before departure. I live in Scotland and had already purchased a train ticket to get to Manchester, but since the cancellation was notified less than 30 days before the flight, I am unable to cancel or modify my train ticket, resulting in a total loss. Additionally, due to personal and health reasons, I need to be in Turkey on that specific date, so I was forced to book another flight from a different airline within the 20-day window, costing me twice as much as I would normally pay.

I bought my ticket from SunExpress a year ago, and I am extremely disappointed with how this situation was handled. Customer service has been unhelpful, unable to escalate the issue to higher management, and only advised me to fill out a form. I did submit the form, and it has been almost 20 days with no response or compensation for my losses. I have flown with SunExpress multiple times and never encountered such an issue before. This has been a truly frustrating experience, feeling like I paid to be inconvenienced. I request that SunExpress take responsibility and compensate me for the financial losses caused by this last-minute cancellation.
