Akbar Travels — Regarding commission

I am a agent tof akbar travels . When i booked train ticket the commision is non ac rs 20 and ac rs 40. When we booked ticket company also deduct money from my commision company told half commision is for company plus gst. If we recived rs 4o for ac train booking per pnr company give me only rs 16 after deducted gst and half commision. Icontact irctc they told me no deduction from ur commision then why akbar tarvel deduct
