Schema: CREATE TABLE Rent_Arrears (council_tax_id VARCHAR, cmi_cross_ref_id VARCHAR); CREATE TABLE Customer_Master_Index (master_customer_id VARCHAR, cmi_details VARCHAR); CREATE TABLE CMI_Cross_References (cmi_cross_ref_id VARCHAR, master_customer_id VARCHAR)
Question: What are the renting arrears tax ids related to the customer master index whose detail is not 'Schmidt, Kertzmann and Lubowitz'?
SQL: SELECT T1.council_tax_id FROM Rent_Arrears AS T1 JOIN CMI_Cross_References AS T2 ON T1.cmi_cross_ref_id = T2.cmi_cross_ref_id JOIN Customer_Master_Index AS T3 ON T3.master_customer_id = T2.master_customer_id WHERE T3.cmi_details <> 'Schmidt ,  Kertzmann and Lubowitz'
