IDBI Bank — unauthorized deduction

Address:	122001

I had deposited a cheque of 4l o[censored]bi, in my account in idbi bank, sushant lok branch on 12th feb. The amount was credited twice to my account without having been cleared by ubi bank. The amount was first credited by idbi bank on 13th feb to my account & was debited on the same day. Then it was again credted on my account on 16th feb & again debited on the same day. However, this time a charge of rs.295 was deducted as there was a signature mismatch.
Now due to signature mismatch ubi can deduct amount, in fact they have deducted rs.260 for the same. But what is the logic of deducting this at idbi beank's end. The is due to wrong operation at idbi bank's end for crediting the amount twice without having it cleared by ubi bank.
This has been confirmed by chief customer complain manager o[censored]bi & the same is attached herewith for your reference.
The matter if forwarded to chairman idbi bank on 21st march but no response received so far.
