Received a call from this number and I disconnected it without answering. I phoned it back and it went to a voicemail. I hung up. I then received another call from this number and it was a man. He said he had received a call from my number. I told him I was phoning his number back because I had received a call from it. He denied phoning my number. He read my number out to me and asked if it was my number. I said "correct". He asked why I had phoned him. I told him I had disconnected his call when he phoned earlier and I decided to find out who was calling me. He argued with me that he did not phone me even though I have a record on my phone of his call. I then told him I was blocking him and I hung up and blocked his number.
