Patta transfer not moving because of wrong survey number

Sir, After 2 year of corruption struggle from a guy who transfered our home patta to his name back in 2014 somehow (because he is basically friends with everyone at tasildar office to registar office, since he used to sit and write deeds there), he is also our next house neighbour. After a minor conflict with my dad, and when my dad realised our home patta is on his name, my dad decided to appy for patta change. when we asked, how was it changed, the VAO replied that some UDR guy randomly alloted. So we decided to apply and took 1 year to get surveyor on ground for verfication after several request and visit to VAO office and tasildar office. Finnaly when it was about to be processed, now the head surveyor at tasildar office says, the survey number is wrong and we cant process it, when we took it to the tasildar, she says she will look into it, but clearly seems not intrested in taking any action, she says she has to send some request to RDO office to approve. After searching online i understood that wrong survey number can be corrected via applying rectification deed, but the problem is , its a settlement deed from my grand father to my father and my grand father has passed away. So im not sure how this will work out, and should i take this to a civil court ? The worst part of all these is how these friends of friends in these government office people make normal people suffer because of personal vengence, delaying the application wantedly and giving random reasons everytime. My dad is in deep depression because of this.
