Air Arabia — mismanagement of air arabia staff and pushing the responsibility on the passenger

I travelled through fligh g9 0414 from coimbatore to sharjah and had to catch the next flight to riyadh g9 0151, when i reached the air arabia staff for enquiry to understand how should i reach my boarding gate he asked me to wait through the security check in line to reach the gate-20 and i did without waiting for a second, when i reached the gate they told me that my flight departed and when i reached the transfer desk i was treated cheaply as if i had missed the flight intentionally. It’s not my case, i am veteran traveler who cannot make such silly mistakes and the way the staff in the reservation desk handled was rude and cheap. I never expected such irresponsible behavior from air arabia staff in a international airport.
It’s a complete mismanagement of air arabia and pushing the blame on the passenger to shift the ticket cost to the passenger where the issue is from air arabia staff. Even when i was ready to pay for the new ticket the staff gave me a false information that there was no ticket in the next available ticket, but when i approached sata they gave me a ticket seamlessly for 900 aed. So i was shocked by such an irresponsible behavior of international airline staff.
There were three staff in the transfer desk counter a female staff and two male staff who all were rude and were repeatedly blaming me for the delay rather understanding that i was made to wait in the que by the airarabia staff.
If you have the airport footage you will know how i was guided to stand in the que by the airarabia staff and was blamed later by airarabia staff that i delayed.
If you really care for your passenger and when there is a genuine complaint, i wish you to take actions to improve the training of your staffs that is eligible to work in such environments responsibly. If you want me to prove my case, i can do so in any court or by international arbitrator. First i wanted to see your response for such cases.
