Sirs,
Serious complaint against citi bank
I have a serious complaint against citi bank (Citi card service). My hdfc bank a/c was debited by ecs mode for the amount due to be paid to citi card on 31/8/17. Till this morning (4/9/17) my citi card credit limit is not updated (Increased by the amount paid to ciiti bank). When talked to citiphone officer twice, both quoted rbi rules. Once it was told to me that it would take 24 hours to reflect n my citi card and at another time, it was told to me that it would take 3 working days to do so.
I am confused by these information given to me and i request rbi to tell me (Emailing to me only the relevant rule) exactly as to how much time it takes to effect ecs payment.
I also request rbi to take serious and prompt actions against citi bank if the bank has not followed rbi rules in this case.
I can provide more details if you need to investigate the matter, on hearing from you.
In any case, in this modi digital age, why ecs transfers do not take place immediately. Rbi should revise its rules to make transfers faster, say within a few hours.
I shall appreciate your response to this email soon.
