Regarding neighbour of my own building not allowing to run trade.

Hello sir,This is mithun from bangalore..i have few clarifications which i have listed below: 1. I own a building which has a road width of more than 50feet in which am running Paying guest accommodation business.The bescom,BWSSB and building tax all are commercial with regard to my property.I have a problem with the neighbour as he has filed series of complaints against my business which are completely false with jealousy or some ulterior motive. I have got the trade license already without his consent as he was not willing to give the consent to start my business. So will the trade license be cancelled if his complaints to BBMP continues??? 2. So what is the provision to overlook such consent of neighbour and run my trade peacefully?? 3.Am starting a small restaurant in the basement of the same building now.Again without a proper reason the neighbour has issued complaint and has asked BBMP stop the restaurant.So Can a restaurant be opened in the basement with cooking area located in first floor of my building??? Is trade license issued for business in basement?? 4. Finally what can i do to run my businesses peacefully without the intervension of the neighbour? Please help me with this regard sir...Will be waiting for your reply...Thank you!
