MENA region players can buy pack with BR region price on web site ?

I’m in MENA region and in Steam I can buy the packs with regional price which I already buy twice but cuz of the support team I can not access my account since week, I couldn’t play. So I create a new account this one and I want to try to buy supporter pack from website (cuz my steam account still locked) but there is no regional price for who living in MENA region. Can I buy it from BR region on website ? Prices is similar but I dont wanna get second account lock. When my steam account is unlocked I’d like to merge these accounts. I just wanna know if I buy packs with BR regional price can I play it in MENA zone or not?
