Just got a call from this number. Usually I ignore calls like this but unfortunately I'm unemployed and have applied at numerous companies. Anyway, I answered and there was no one at the other end of the line. The system may have been one to locate active numbers (if you answer then your number is put on a list of active numbers and then they sell the list).
I get random calls like this all the time. I don't do mobile banking anymore because of having my credit card info stolen just after one of these calls. I answered and they immediately hung up.
I continue to get calls everyday from this number which I NEVER ANSWER. I have an Answering Machine set to pick up on the forth ring but this number hangs up before the machine picks it up. I am reporting this number in the HOPE that someone can stop this continuing Robo Dialing Operation.
