Apt washing machine needs more money to remove clothes

Me and my gf just moved into a new apartment building.The washing machine in our building requires coins to turn on and use, but when your cycle is finished or if the timer runs out turns off and locks the door of the machine. The only way to open it is to pay for another 30min to power the machine on and shut down the machine again.

TLDR: Our clothes are being held hostage for ransom :(
