Axis Bank
Sending communication at wrong address

My sister has S/B account in Faridabad Branch of Axis Bank. She had deposited a cheque in the drop box at Sahibabad (Ghaziabad) on 19.5.10.After a few days a telephone call was received from the said bank that there was some mistake in writing the cheque and that the same was being returned by courier. When the cheque was not received after quite a few days, inquiries were made and it was told that the cheque was sent sent at her old Faridabad address, when my sister had already got the address changed five years back and was receiving all communications including cheque books etc at the new address at Sahibabad. Now one week has lapsed but the cheque has not been received back from the said bank.
