Auto and general call center problems

Always bragged about how awesome my insurance company is (Auto and General), after the frustrating call center experience I had this morning I'm not bragging anymore. I was sent from call center tocall center just to get a quote. Then I was told that my Ford Ranger 3.0 TDCi does not exist. Then went through a whole process just to find out that my vehicle must have a tracking device. I wanted to add 3 vehicles and as I did not have a tracking device on the Ford, I told the agent to stop the whole process as it is pointless to continue with the other vehicles if I cannot insure the ford. Had to explain this about 3 times very nicely and gently to the call center agent before he understood what I'm saying. Ithen asked to speak to the persons in charge of changing an address of an existing vehicle. Was put through to another agent (turns out to be one of the agents I spoke to earlier on) , told him that I want to change the address of an existing vehicle. He then proceeded to explain quite irritated that he cannot add the 3 vehicles to my policy, as they have a different address. So I had to reiterate (also about 3 times) that he must ignore the 3 vehicles I wanted to add, the reason I'm speaking to him is to change an EXISTING vehicle. Was quite frustrating having to explain everything the way I'll explain it to my primary school learners
