Cancelled trains and delays

Hello! On Friday I took a direct train from Deventer (18:45) to Roosendaal (scheduled to arrive at 21:03), but the train got cancelled in the middle of the trip in 's-Hertogenbosch (20:07). Since this train was cancelled, I had to get a new train for my desired destination. Then there was a train (direction Dordrecht) at 20.33 to Breda and then another train from Breda directly to Roosendaal at 21.15. After I reached Breda station, the train at 21.15 got cancelled again, so I had to wait 30 extra minutes for another train, but instead I asked a friend to pick me up from Breda. I want to know what rights I have. I am currently traveling using a subscription, which will charge me at the end of the month, but since I could not reach my final destination and I had a huge delay in the travelling, because of two cancelled trains, I have the right to ask for a refund.
