Man i had enough with my driving school

I of 18yr old went for driving test and passed the car test but failed in the bike test. So i asked them that when will i get the retest date. They told me that it will be recieved within this month and they said to call for date booking. Now they are telling me that you cannot get test date in this month it will be february when i get the date.(I have my boatds). So i said i wanted only the car licence but not the bike but they are compelling me to take the bike licence. Dear kerala, Is there any way that i can cancel my bike test and only apply for the car
