Section 125crpc Where To File Revision Petition

A Order on section 125 crpc is passed by Kalyani judicial magristrate court ordering a final maintenance amount of Rs.7000/-. The wife has left me on her own will and I have sent 3 letters asking her to come back and I have also mentioned that i earn Rs.16000/- P.M.by way of running a homeopathic shop . But the court has not considered the facts and awarded such a hefty amount. Can i challenge the order in Calcutta High court.Or should i go to district judicial magistrate court. Whch is better option . I have also filled a divorce case on Dec 2018 and as wife has not come so ex party order has been passed and final divorce order will soon be passed . Please help how i can reduce my maintenace amount
