Address:

Sir/mam,
i had obtained education loan bearing no.LICU/01/170100 from corporation bank, kedar brach, villupuram district, tamilnadu in the year 2008. At the time of granting education loan my father had given original sale deed document no.1078/1989 on the file of sro, Anniyur as collateral security. the above said education loan was paid under RIYAYATIV on 27/11/2017. thereafter I had approached the branch manager for return the original sale deed on 04/12/2017 he stated that he does not know about the original sale deed document and the same was no procedure to follow to be given original document . the branch manager stated that i don't know about your original sale deed and you can approach any forum, no one nothing to do for me .kindly i request you concern authority may be directed to return back the original sale deed which is retained by the corporation bank.
thanking you,
