IDBI Bank — My details reflect in another customers details

Address:

Thane, Maharashtra

Myself Zankar Sudhakar Borse having a loan account in your bank (A/c No.[protected]).

I have found the multiple letters of IDBI bank statements of customer named as Mr.Harendra Pal Singh (A/c no.[protected]). in my letterbox.The letter reflects my mailing address, my registered mobile numbers which is very BIG MISTAKE from IDBI Bank.(COPY OF LETTERS ATTACHED).
I have tried to contact your branch on 25393906/07/01/17/19 but nobody picked up the phone even during working hrs.
Finally I had visited RAC, GHANTALI DEVI MANDIR, Thane branch on12/01/15, i met Ms. Akshada, She verified Mr.Harendra Pal Singhs A/c details and my details also.
After verification and confirming my communication details, when she opened the details of Mr.Harendra pal singh's account, it is found that all my communication details i.e.My both registered mobile numbers ([protected] and [protected]), mailing address and email ID reflected in his details.

Ms Akshada kept the original copy of letter of Mr. Harendra Pal Singh with her for investigation and rectification but she didnt gave any acknowledgement or any request or complaint number after discussion with branch manager.

In addition to this, I am regularly receiving SMS from IDBI bank on my mobile number [protected] regarding the EMI due of loan account (**********05791) which is not belongs to me.I have already sent a request regarding the same to your customer care toll free number approx 6 months before on [protected], but still i have not got any reply from your bank.

Now its been 1 month but still no reply from the RAC thane.Still i am receiving the SMS from IDBI bank of any other account holder.I am continuously calling on[protected]/07/17/19 but nobody picks up the phone.

You are requested to investigate this matter and revert as early as possible.
