In which court should i plead (collector or Higher Court)

I bought a land 0.95 acre from 2 brothers(47.5 decimal each) 4yrs ago khasra no. 124/1, 124/2. and when i applied for name transfer the patwari told its not possible because there are already illegal homes built there and people are living in it. after deeper introspection i got to know that sellers actual land was a little farther from where it is shown in the patwari's sheet. it got shifted to new place after the bandobast and the sellers dint have any knowledge about it. I also got to know that sellers' third brother had his share of 47.5 decimal land with khasra no.124/3 which he got settled with the govt. under rule 89 of MP govt land rules (Truti-Sudhaar). His share of 47.5 decimal land was shifted back to original place and he sold it to someone else. After this, Since my name was not transferred on papers, my sellers applied for truti sudhaar as well like their brother in SDM court but the RI wrote a note in his report that there is no land left in old khasra number because a school and panchayat bhavan has been made there so truti sudhaar in this case in not possible. Even the villagers have passed a gram sabha report on sellers' name stating that sellers' actual land was somwhere else its its govt's fault that they shifted it somewhere else and that the land's current position cannot be given to them because villagers have been using that land for gathering purpose since decades. what should I do?
