You are absolutely correct. If your landlord did not have you served yet, you have no responsibilty to pay another fee especially if a) that fee is not included in your lease and b) no proof of filing has been shown to you. Further, you may wish to contact your local consumer protection agency that handles such matters. Keep in mind that while your landlord cannot evict you now in retaliation for contacting the consumer protection agency, the fact remains that the landlord does not have to renew your lease.  So think about your next steps but remember to put everything in writing.
