Cartrack. Very annoying caller, who spoke in a manner that I found difficult to understand. The more I asked him what the call was about, the more he was asking who he was speaking to. He then rattled off a speech that I could not hear, then promptly asked me what car I drive. I basically told him to get stuffed and hung up. I blocked the number, but I see on the blocked calls list that they tried to phone me again another 3 times.
