Hi - this number has been repeatedly calling us every afternoon for several hours. Usually there is no number on caller id because they hang up after 3 rings. Yesterday (May 26, 2008) they called - I answered quickly and a man asked for my husband. By the time I passed the phone to him, the caller hung up. We were out during the morning and the number was on my caller id, with "O2C" as being the caller. When I tried to call the number, the operator said the call could not be completed as dialed or had been disconnected. So this is my search for whomever it is.
