Forcefully Parking Before my Shop and Blocking the Entrance

I have my Shop opening on public Place/Road. As such there is no footpath but only two steps attached before my shop. After climbing down from these two steps I get on the public place (around 5 feets before my shop) which also have one narrow road ahead attached to it. Some adjacent shop owners and also the Building Society people forcefully parking their Motorbikes before my Shop and blocking the entrance so I and Customers walk around from other side and get on the steps from other side. Besides, it is very difficult for me to get my goods inside through Tempo/Truck. When requested to keep some space to enter the shop they fight with me even attacked me twice complaint given to local police (First Complaint through email and Second Complaint personally by receiving Stamp) and in one incidence it was danger to my life as a group of people threatened me with life saying come out of your shop we will show you then I had to call police help-line no. 100 the operator asked me to be there inside the shop till police reaches (audio recording available), then police came and rescued me. Then I submitted one more written complaint to police. After my first complaint through email when I reached police station to Submit hard copy they deed not received it but registered only NC under section 323, 504. I want to know under what section this offence fells. Can IPC 339 (wrongful Restraint) along with IPC 340 (Wrongful Confinement) is applicable here ? Does, Clause 122 of the Motor Vehicles Act (1988) applicable here as road is norrow and in emergency, such parking will cause obstructions to Fire Fighting vehicles etc. Also let me know, how I can get relief. Note : Video Recording is available of the incidences
