Not Happy with ASSISTANCE given

I have made 4 calls and sent 2 emails to debt busters regarding my maternity leave and have not recieved an answer that is actually of assistance.

firstly when i signed up i was told can cancel anytime now i see hear that i cannot cancel even if i am willing for my interest to go back to the way it was and making arrangements with my credit providers regarding my accounts.......

firstly the reason for cancellation is due to the fact that i will be going on unpaid maternity leave and not sure about when UIF will be paid or if i will get it for the time i will be at home as UIF is not dependable........

my question is this

what will happen to my account if i cant pay it for 4 months ? will you guys keep debiting my account and letting it go into a negative ? i dont want to cancel my account but i need assistance as to maternity leave because there wont be funds available and unpaid debts will reflect bad on me regarding bank charges and all ?

can someone give me some sort of assistance as i need to know what i must do by when and how my maternity leave might start in November 2018
