The bank accepts the medical reports submitted by you of your mother, Mrs McGonagall, and understands that she is not in a state to access her locker.
Hence, the bank has authorized you as the representative for your mother to access the locker no ECX2347 and the belongings in the said locker. We are sorry for the delay to provide you the access; but the time has been utilised to ensure the safety of your belongings in the locker. We are hopeful for your trust and faith in us like your mother.
