Rto India — Rto bangalore (East) for declining to receive the registered post sent to them via india post

Address:

560038

As per the requirement of rto-bengaluru (East), we send all the document in the name of dy. Commissioner, rto-bengaluru (East) via india post on 7th feb 2017 & the same has been delivered on 9th feb 2017. Now, rto-bengaluru is declining that they are yet to receive any registry post. Now they are saying we need to come down to bangalore from baroda personally & handover the document whereas earlier they said we need to courier via post all the document. Please help & guide us further against such things.
