rip off merchants

I have been with elephant for 14 years, owning a classic mini and with 14 years no claims. I recently brought a Seat Leon fr while I was in the process of selling the mini I asked if I could insure both cars on one policy, which they agreed to quoting £61 pm for both cars, not bad considering I was paying £42 pm for the mini alone. On selling the mini I was contacted by elephant with my new policy quoting £58 pm for my Leon, when asking why it was almost as much to insure one car now as it was two cars, they said it was because the Leon was a higher performance car than the mini (even though they were happy to insure both on one policy for £30.50 each)
After cancelling some of the cover on my policy, (as this was the only way they would bring the price down) I settled on £46 pm. This continued for two years, with the car being parked on a small driveway. This week we moved to a new house, with the car being parked outside of the house, in a quiet area. This has given them the excuse to bump my insurance up to £55.22 pm now, even though my g/f has just notified Direct line of the change of address on her insurance and they have knocked £6 off her insurance, even though she has only been with them 12 months and has 4 years no claims.
My policy is up in March 2017 and I won't be going back, as in 14 years my insurance has gone from £745 to £480.

So judge for yourselves.
