According to Bell Aliant's terms of service, they give you 30 days to cancel without penalty.
You might reference that. However, it's basically up to them, so appeal to their compassion.18. Where the Customer purchases the Service at a contract rate for a Contract Period, and chooses to cancel their service prior to the end of the Contract Period, the Customer will be charged an early termination fee of $99, which is not a penalty but rather an estimate of anticipated damages which Bell Aliant would likely suffer as a result of early termination. This early termination fee will be waived where the cancellation occurs within the first 30 days of Service, or as otherwise determined by Bell Aliant in its sole discretion.
