Refinance denied

I'm so greatful to MFC for allowing me to pay 50% of my installments for 3 months as a result of a new working since lockdown. Since covid-19 and it's effect are here for sometime, I had requested MFC to refinance my car so as to reduce my installments. They have told me that they don't do such and I find it hard to believe that. My normal installments shall continue. I'm requesting help from any financial institutions for help
