Hi, about the Schengen visa situation in Turkey you can find articles like these that describe how the appointments are on the black market(In Turkish but I'm sure AI will do good job translating):

On the social media the anecdotes differ but some say they were able to get the visa appointments bots, others say it was agency personel selling it to them under the table. Maybe its really the agency personel, or maybe it's people running bots to snap appointments and sell those pretending to be from the agency - can't know for sure but there are multiple services where people purchase appointments unofficially.
In general the news situation in Turkey isn't very good as with the law enforcement but as you can see even BBC took notice.
Generally speaking, these visa agencies are very unfriendly and unreachable. They seem to just collect the money, provide no personalized help at all. My GF had some questions about her US visa application, we were not able to reach VFS Global. The phone numbers provided don't work, it's not even like taking long to speak with a human, the phone just gives you calling error.
She previously used the same company for her Schengen visa for a company event in Paris, of course unreachable again and no appointments available. Because she works at a French corporation, she was able to ask a high ranking French person in the company who has a contact with the French embassy and they arranged the appointment shortly.
