Address:

683521

I have NRE&NRO a/c with kotak it was said to me while opening that it should be jointly maintained now my NRE account was maintained so well from last 4 years now last my LIC bonus cheque credited 5000 rs to NRO a/c when i checked the whole amount is deducted from my NRO account for non maintenance of minimum balance charges.
Have no other issues with bank would like to close everything from the bank at the earliest.
Dont like to have more surprises.
