I finally claimed my airdrop in the second round of airdrop I experimented by changing the wallet address where I can claim my airdrop, on my first try I was charged 0.75 BNB which is useless to proceed because of the very high fee, but when I changed my claiming address to a new one I was only charged with 0.002 which is way to low from my previous attempt, I recommend to those who are charged with a very high fee to change their claiming address and try again, it works for me.
