While signing up for bb unlimited I mistakenly ticked 'with tolls' box.

I just wanted the slingshot BB service on the telecom phone line i had stated with the telecom account holder of that line paying for the calls like before (its actually a fax line so it doesn't make too many calls anyway) But I'll now pay for the slingshot BB service.
 
Ive cancelled the toll service but am wondering will that return the payment of any calls to the phone line account holder again?
