Unreliable statistics used to increase my monthly premium by more than R200

I have been with Nedbank insurance for over year now. I insured a 2012 320i BMW and i was paying just under R1400 pm and i upgraded the car to a 2016 320D M Sports and the premium went up R1850 pm in November 2017. My 2012 BMW was parked in an open space in a access control complex. I understand that it was exposed to many risks and i them decided to move to a complex which still have access controlled gate with camera reviews and my car is now parked in locked-up garage. The new complex is just 3km away from my previous address but to my surprise, the premium was increased by more than R200. When i asked the consultant, i was told that the new area has more risks such hijacking, theft, break-in and smash and grab. All this information is said to be from police statistics and other stats SA statistics which is untrue. The area that i am staying has no hijacking or break-ins and it is the most secured village. This makes me believe that i am being punished for being safe.

The problem which i picked up is that the area is registered under Nigel while it is under springs in the east rand. I tried to explain to the consultant but all of them couldn't help and they said they only rely on the stats of the area. I think insurance companies need to send representatives to the areas where clients reside in order to make good business decisions.
