dumbfounded

as if struck dumb with astonishment and surprise; "a circle of policement stood dumbfounded by her denial of having seen the accident"; "the flabbergasted aldermen were speechless"; "was thunderstruck by the news of his promotion"

आरसीबी के सोशल मीडिया हैंडल्स- फेसबुक, ट्विटर और इंस्टाग्राम को देखने के बाद प्रशंसक आश्चर्यचकित थे।

Fans were left dumbfounded when they saw RCB’s social media handles- Facebook, Twitter, and Instagram.
