Bullying tactics from Absa vehicle finance service department

Absa vehicle service department is the most insensitive cold and heartless department. My son is in ICU and as a result i have been admitted with him. Someone from the department called and I explained to her I couldn't talk because my son is not well. My car is not owing and I have have insurance. Irregardless of me telling them my son is ill they persued non stop trying to force me to take their insurance. I have a right to choose my own service provider they have no right to force their insurance down my throat. The need for absa to bully and control its customers and our accounts is really disgusting for this reason I stopped receiving my salary through the cheque account they offered. I am so disgusted and disappointed by absa.?
