Citibank — No reason to reject

Address:	41000
Website:	Citibank credit card

I'm sure my income is high and i am eligible to apply a credit card, i went to sunway and they had a roadshow and ask for my ic and everything to apply, after a week i got a sms stated its unsuccessful.As a customer, we need to know the reason, i called bank negara they said my account is okay n no blacklisted.when i called citibank, they said they dont know.the girl who answered just mentioned we rejected and cant let u know.U mean u rejected for no reason?what an useless citibank, stupid customer service.And simply reject cases.this really makes me fire and end up i will not recommend citibank to anyone!
