Qatar Airways — Booking reference QRZP7L

I was recently not allowed to board Qatar airways flight from Bangalore to Damman on 1st March. Booking reference #QRZP7L.
I was informed that my RT-PCR report was more than 48 hours old from the time of arrival in the kingdom.
As per Saudi government travel requirements, RTPCR test is supposed to be taken within 48 hours before departure to Kingdom.
My swab sample was infact taken within 48 hours before departure time.
Therefore, I had to re-book the same flights on 03rd March after paying a penalty amount of SAR 434/-.
The rtpcr test timeline should be based on time of departure and not on arrival time as per latest Saudi Arabia government travel requirements.
I want a full refund of the above amount as I haven't violated any of the Saudi travel requirements relating to the rtpcr test.
If I don't get a refund, take it from me that i will not take Qatar airways flights in future.
