greek subs – help!

Hi there, I was just wondering if anyone is having an issue with regards to greek subs. For example, I am watching a series which started in 2015 (Aquarius) and has already finished and there are subs for the first couple episodes and then nothing. This is not a one time occurrence and it is very frustrating to start watching a series to then find out there are no longer greek subs available. I have all the add-ons for greek subs, if anyone has any suggestions or aid regarding this matter it would be greatly appreciated. Thanks.
