Caller: James from unknown

Rang & asked to speak with the fleet or operations manager, only identifying himself as James, did not state where he was from. Could hear call centre in background. When asked what the call was in regards to, he stated GPS tracking for fleet etc.
I asked if this was a sales call, he confirmed yes. I proceeded to tell him we are not interested, as we are already happy with our provider of these services. He then kept pushng, asking if I was the one in charge to make the decision. I stated again, we are happy with what we use. He repeated his same question. I hung up. would not take a hint 5+ times
