You pays your money and you takes your chances. In this case it seems you preferred to take your chances by purchasing non-changeable non-refundable tickets, apparently for both your flight and your means of getting to the flight.
It's a bit like putting all your eggs in one basket, and a cheap one at that, and hoping that the bottom won't fall out.
That timetables can change shouldn't come as a surprise as the possibility is clearly mentioned in the terms and conditions that you accepted when you purchased your ticket. You also accepted that you yourself should check if your flight is rescheduled.
You may still get a notice from Ryanair that the schedule has changed, there is still 2 months to go, and then again you may not. That Ryanair don't do customer service shouldn't come as a surprise.
Nobody conned you. You pays your money and you takes your chances.
