Phoning for new clients telling me I am rude

I will be worried if I have to phone around for to get new clients and when I see I am not interested they tell me that I am rude. They wanted to know what will I do if my car get ****** I said it doesn't concern them as it is my personal information and it doesn't concern them I am told that I am rude. I said I don't have time for this because I have work to do and I was told once again I am rude. So I've put the phone down as they are wasting my time and I am very disappointed in the netstar company. Please get competent and not arrogant people to do this job and don't irritated people. Cheers.
