Missed re enrollment for 2nd year, course terminated, what should i do?

i m a continuing student in Westminster university facing financial hardship, so i couldºnt pay the tuition fee fully. therefore the finance department restricted my account so that i couldnt re enroll untill my payment was complete. therefore i wasnt able to complete my enrollment for the second year. they have passed the debt to STA debt collection agency and i could set up na installment plan with them, but i recieved an e-mail that because you havent enrolled on to the system, your university terminated, so i was wondering what does that mean? am i course terminated and cant return to the university or if i pay my tuition i could re enroll next year? if any one having or had the same difficulty as me, can they clearify my situation. What will happen, i tried to talk to the finance department as well to see if theres any way i could arrange an installment plan but they didnt accept in any way possible to arrange an installment plan and threatened that if you dont pay the whole amount it will be passed to an debt collection agency and they will raise so much more Money. please i need some advice? Am i course terminated or can i re enroll next year once settled my finances.
