You should have an attorney review the correspondence. In most residential rentals in Chicago there is a rule that no lease can require the tenant to give a longer period of written notice to terminate the lease than the landlord, unless it is disclosed in a separate written notice. The landlord only has to give the tenant 30 days' notice in advance in writing to not renew a lease. So, if your lease required you to give 60 but not the landlord, perhaps that is an issue you could work off of. All that aside, if you did in fact give the 60+ day required notice and did not really withdraw it, that might also help you. It depends a lot on what the written correspondence looks like, and if this property was covered by the Chicago Ordinance or not.

I agree with Mark's answer. It sounds like you complied with the 60 day requirement. Furthermore, you may have protections under the Chicago Landlord-Tenant Regulations.
I recommend sending a written response to the landlord/management company indicating that you disagree with their assessment - and you complied with the lease. Also indicate that you dispute the fees they are trying to charge.
