RTO India — rc card not received even after 1.5 years

Address:

Kasthuri Nagar, Bangalore, Karnataka

I have submitted my original rc card and all other needed documents aand required fee for hypothecation removal on 04.08.2018 at rto bengaluru east (Ka03).
I was given receipt for this. I visited 3-4 times until 6 months after submission date.
They informed that they already sent my rc card in indian post. But till date i didn't get the card. I even checked at post office for the speed post number provided at rto office and post office declined saying that no such document/post received by them.

I checked online for the given speed post acknowledgement number at rto, but its wrong and no such consignment.

Request you to address this issue at the earliest.

Thanks
