If there’s a disagreement about deposit deductions, try to reach a solution by calmly discussing it with the other party.
A tenant can apply for dispute resolution if the landlord kept all or part of the deposit without the tenant’s written permission. The tenant's application can be made within two years of the end of the tenancy – as long as the tenant gave the landlord their forwarding address in writing (within one year of the end of the tenancy) and the landlord did not return the deposit or apply for dispute resolution before the 15-day deadline.
