Blockage of my car Creta since last 40 days by the builder and his son using old Maruti 800 car

Since 5 and a half year, I have been parking my car in a comfortable parking space as per the verbal affirmation of my builder and owner . Initially they told us to park there and with confidence told that they will demarc our parking area there only but 6 months back they demarcated it in a slot from where it is very difficult (next to impossible) to enter or exit the park in that garage, so I refused to accept it as my slot. In the registry paper and sell deed it is mentioned that the parking is demarcated at the time of purchase but it wasn't so. When we enquired about it they told us that the parking space is fixed only demarcation is left and will be done very soon. In the span of 5 and half years they never disturb me in regard with parking area. On 12th February 2022, the builder and owner parked Maruti 800 in front of my car and have blocked my car since then. On contacting local police I haven't been able to free up my car. Now it is the time of car's servicing but because of the blockage I am not able to do that. In response my car is gradually becoming dysfunctional. Also there is an environment of fear and terror in the premises. With regard to the given situation what next step I should take to free up my car ? Also can I claim compensation for repairing my car?
