I Demand Skyscanner Fix Gotogate's Unauthorized Flight Change

I purchased a ticket for a June 10 Ankara–Jeddah flight through the agency Gotogate, which I was directed to via the Skyscanner app. The direct flight I booked was later canceled. Even though there was a direct flight from Ankara to Jeddah that same day at 2:45 PM, they tried to notify me and get my approval, but despite the fact that I did not agree to it, they rebooked me onto a connecting flight instead, and I'm now dealing with the fallout of this.
Throughout this process, I contacted Gotogate customer service multiple times, but I haven't been able to get anywhere. I purchased this ticket trusting the Skyscanner app, so I expect Skyscanner to take ownership of this problem and resolve it.
My request is to be moved to the same-day direct flight from Ankara to Jeddah at 2:45 PM on June 10, using my existing reservation. My reservation number is 1123351065. I need an urgent response on this matter, and I want this problem resolved.
