Party not paying for Goods purchased

Dear Sirs ,
I am a manufacturer and sold wooden doors to a party for bill amount 6 lac and since one year he is not returning phone calls or paying the balance amount of 4.5 lac. I sold him material on good faith because earlier he paid cash on the first deal and promised to pay for the second deal in a weeks time.
His firm was gst registered in my town YamunaNagar(Haryana)
Later I found the gst was registered on a bogus rent deed and he had no Godown at all and only a small rented single room.

After I billed him the invoice along with way-bill number and freight bilty he sold the same truck load material and billed an invoice to another party.( I have details of the other party)
In his gst returns he did not mention the purchase he did from me and filled the gst Return of nil. ( That means he did not register Amy purchase in his gst return that he made from me, or the sale he did)
can this be fraudulent or 420?.

I consulted an adv and sent him a legal notice to his native address.
In the meanwhile I even filled a case on msme samadhan portal.

I was told I will have to file a civil case of recovery and deposit a court fee.
Sir, my question is how much will be the court fee and under what legal laws can I file the case?
will I get my money back? what if he doesn't take the summons since I live in yamunanagar Haryana and he has gone back to his native place Bihar.

Thanks
