Address: Thrissur, Kerala, 680664

My name is diffin. Last 7 years i am a nri account holder of sbi, kodungallur branch account number [protected]. Using my this account i am doing so many online transactions. And every month i am transfer money to my this account. For all these transactions i am not receiving sms alerts from sbi. From the beginning onwards i am not receiving any credit and debit sms alert. Several times i give complaint to the branch manager still now it is not solved. So many times i directly go the branch and update all my details. For this service bank is taken service charge from my account
