Paid for a course and cant get any refund now

I just thought id ask here and see what people think more than likely i wont get any refund,but i signed up for a classroom based photography course that costs €2600 i paid €350 deposit and then its 9 monthly payments of €250,i started the course in February but due to work commitments i couldn't continue it and i never went to the second class,last week i emailed them and asked to be moved to the home based course that costs €1280.

After looking at the home based its way overpriced and very expensive for what it is,yesterday i asked to cancel and i wanted a refund,i paid €850 in total that's the deposit and x2 monthly payments.

This is in their T&C's when i signed up and they will not give me any refund,even though i only attended one classroom course.

4. If a home study student decides to withdraw from their course within 14 days of enrolment they can request a full and complete refund of course fees paid. No refunds will be issued after 14 days.
5. If a classroom student decides to withdraw from their course for any reason they can request a full and complete refund of course fees paid if the request is made within the following timeframes:
Before the second class for Saturday classroom students Before the third class for weeknight classroom students
No refunds will be issued outside of the timeframes specified above.

Now this morning my only options left are
1 - You can cancel your course now and I can arrange to stop any future payments.
2 - You can place your course on hold and can revisit at another time when you have more time to commit.
3 - You can continue with your course and pay the remaining balance.

If i cancel now im basically just giving them €850 for nothing,the other two options im just wasting my money on a very expensive course.

So what do people here think any advice on what i can do?
