RTO India — RC is missing

Address:

8-4-379/200/S/1 NRR PURAM STE-1, BORABANDA

I have bought a bike 6 months back but the RC is still not delivered to my address. I went to the post office, they said it's still not dispatched but in online Website it is showing dispatched. And then I went to the RTA office, i asked there my RC they said they don't have it go and ask in local post office. Again I went to post office then again they said the same thing that it's still not dispatched. Please help me with this problem. My RC's speed post number is (EMs) EN[protected]IN. Please do help.
