Jay_vh , via OnePlus 5T , Jul 15, 2020 : They couldn't deliver oneplus 8 pro in market due to their busy schedule cause they have to launch new product in market cause they are busy for marketing oneplus nord ane oneplus buds. so i guess they don't care about potential buyers of oneplus 8 pro. and pre-booking are one kind of con skim by oneplus cause I'm victim of their skim. due to their limited supply i couldn't buy and now they are not taking any responsibility regarding my pre-booking. customer support team by oneplus they hang-up any time during call.
