Mysteriously R&B department has vanished my land-Kollampally village,Narayanpet dist, Telangana

Sir, as per my old passbook , I am supposed to have 3 Acres 6 Guntas of Agricultural land at Kollampalle village, Narayanpet (Mandal & District), Telangana. However, to my utter surprise, found that the 5 Gunta land is missing from my new passbook (after online entry). Now, i have only 3 Acres 1 Gunta land in my new passbook. On the same, approached my Mandal Office on 22.Jun.2019 located at Narayanpet & met VRO. He has expressed his doubt stating the so-called 5 Gunta land might have gone under Road construction by R&B department. Moreover, VRO is clueless about the exact reason behind such deviations. So far, approached my Mandal Revenue Officer (MRO), Collector, Roads & Building Ministry, Revenue Ministry, Chief Minister Office & at last Minister for Road Transport & Highways of India VIA EMAIL To my mere surprise, all the above mentioned officials were either neglecting my concern or in sleeping mode. Almost, 30-days passed till date & no one is bothered to at least reply a courtesy mail or a call. ITS SIMPLY PATHETIC AND DISGUSTING. HOW TO GET THE THINGS DONE, PLS SUGGEST
