Where i bought one used car last month and approached the concerned jrto, tripunithura on 13.09.2018 to effect the ownership changes in the rc.
Accordingly, they made the name change and forwarded me the rc of this vehicle on 01.10.2018 as per the attached speed post track report, and i got the same only on 03.10.2018, where the rc issued date was 28.09.2018 (Which is mentioned on the bottom of the rc)

In-order to regularise the same in the insurance policy, i approached the respective palarivattom national insurance office, today morning at 11.45am, (10.10.2018) and that time the chief manager, as well as the dy. Manager, where not there on their seat and the next in-charge told me that, as now 14 days over, not able to do the same, with out inspecting the car. But the rc was issued only on 28.09.2018 (Mentioned at the bottom of the rc) and as per the attached speedpost delivery report, i got the consignment (Rc) only on 03.10.2018 @17.12.45 pm and to day it is only 10th october, ie, only 7 days over, (Even after not considering the in between holidays) how can i submit the rc and insurance at your office, as the same were already submitted at the rto office for name change?
