Dear sir,
I was having an account (Account no. [protected]) at sbi, nirsha, dist-dhanbad, jharkhand (Bank code : 08748) which i later on closed between the year[protected] due to my transfer from that place. Now i need one certification from branch manager, sbi, nirsha that i was having above account no.in their bank which was closed in the year... This account no. Was given in one of my uti policy and now they require above certification from the bank for redemption of the policy.
In this connection i have sent several e-mail to sbi, nirsha, sent application as well as informed contact centre but with no help from any where. Even the telephone no. Of sbi, nirsha given by contact centre does not exist.
I want to know whether it has become a trend for sbi for not to respond to the customers even after sending several e-mail.
I have two more accounts at sbi which are serving very well.
I will request you to please ask the bank authority of sbi, nirsha to send necessary certification of my account there at sbi, nirsha. I have sent e-mail to sbi nirsha on july 11th, 13th & 19th' 2018.
