ICICI Bank — amount transferred to wrong account

Dear Madam/Sir,

I have added a new payee in ICICI bank (A/c[protected] with below details

Bank: ANDHRA Bank
IFSC code :ANDB0000816
BRANCH: KUNKALAMARRU
NAME: KATTEMPUDI MAHESH
A/c: [protected]

There is type error in account number (big number). However Payee got confirmed where as right A/c is : [protected]

My First question is why payee got confirmed

I have done transfer for 2000/- on june 28th 2018.

While doing fund transfer it should fail, but it succeeded. When you are relying on only account number then why do you need all other details.

I have contacted ICICI branch manager, there is service request# SR[protected] raised but So far I have not got my money back.

Could you please return my money as soon as possible. If this is not going to happen I will have to proceed with Banking OMBUDSMAN /legal.

Thanks
Sahithi
