Cancelled flights and poor communication

Horrible experience, after our flight was cancelled at 1:30am with terrible communication from staff on site and no other communication via email or the app we were forced to hire a car and drive in order to make it in time for our commitments since WestJet (once again with absolutely no communication) rebooked us 48hours later. No one answers the provided contact numbers and when a request for compensation was sent, we received no response. Some money was added to a travel bank but all attempts to contact them for a cash refund have been in vain.
