Bought a Car with tracker charged not fitted no re

I bought a car with tracker charged for and not fitted and when I asked if there was an alarm and remote was told there was an immobiliser and I thought it was all one and the same thing and not an extra that I had to pay for. The extras were put on the invoice which I was happy with but no remote/alarm. What sense is there to have a new car with a tracker but to have to open the door in the dark with a key?<br> I contacted the dealer principal who didnt respond but the sales person said I should have known and asked for the remote and now have to make arrangement to have the tracker fitted and to pay an additional amount for the remote. Sad... Customer servcie and customer care is just not what it used to be.
