SBI — Demanding FD, Termed deposit and much more to provide locker

I Dr. MURARI Johan Mandal have an SB account jointly with my wife at Baruipur Zilla Parishad Building branch in Baruipur South Twenty Four Parganas, West Bengal . When we applied for locker facility the officials gradually increasing their demand and black mailing us. Initially it was 50k FD. We made that! Then it was Saral Sadharan and SBI Life!! We also agreed for that about 20 k per annum for next 10 year. Alas ! Then started demanding Termed Deposits of 50k per annum!!! Where will their greed be stopped! Is it SBI business policy? What higher authorities say? Are people bound to do that compromisations to obtain a locker?
