Citibank — payment is not received

I transferred 7000 from my citi bank account to sbi account through imps. Money got debited from citi bank account but, not credited to sbi.
I called to sbi customer care, they told as it is not received by us we cannot take the complaint.
Citi bank customer care people told as that is successful transaction we cannot do it from citi bank end.
