Should acknowledgement be given by pension paying banks while accepting Life Certificates from pensioners?

There have been complaints that life certificates submitted over the counter of pension paying branches are misplaced causing delay in payment of monthly pensions. In order to alleviate the hardships faced by pensioners, agency banks were instructed to mandatorily issue duly signed acknowledgements. They were also requested to consider entering the receipt of life certificates in their CBS and issue a system generated acknowledgement which would serve the twin purpose of acknowledgement as well as real time updation of records.
