Quick update in case someone stumbles upon this thread through Google/..
I went to a Chase branch and sat with a representative and after hearing my repeated rejections he strongly suggested to wait for ~6 months before reapplying, but once he put my details in the system he found out that I was apparently pre-approved for the Sapphire Reserve so he strongly suggested that I do apply (he said preapproval means ~%80 chance that they'll accept). After submitting and waiting a few days, I was told that I was accepted and I just received the card.
My score that's visible in the Chase website (Transunion) is 745.
Hope this helps anyone and thank you everyone for replying to this thread.
