Disgusting service Ethel my lady

I called in to test my vehicle tracking device as required. A lady by the name of Ethel answered and after verification told me that She could not locate the car. She offered to call me back in 15 minutes, but when I asked what if the car was ******? Would they still tell me that cannot locate the car and I would get a call back in 15 mins? She flipped and started giving me attitude, cold transferred me to another dept and I spoke to Michelle. While Michelle was checking the car, as she had me on hold(which Ethel could have done) Ethel called me back and even more arrogant and did not even care when I told her I was going to complain. Its too early in the morning to be giving such attitude lady.
