Interim Maintenance under 125 crpc

Respected experts, My ex wife is still occupying my house and enjoying all the facilities there. She is a working lady and highly qualified. Even then she filed a petition for maintenance under 125 crpc and inspite of telling the facts the Family Court judge had granted RS 5000 as interim maintenance. She is living in my house . She is enjoying shelter, electricity, water, gas , kitchen at my cost. More so she is a working lady. This interim maintenance of Rs 5000 is highly unjustified. Can I file a case under 127 crpc for modification in the Family Court itself or file a Revision in High Court. Kindly guide me so that I get Justice.. Regards.
