This number called my mobile, I answered, no one there so I hung up. Put the phone back on my desk but quickly realised that I could hear people talking to each other in a foreign language coming from my phone. Checked the phone and there was a call in progress. Immediately killed the call. Checked my recent calls and it showed the incoming call which I thought I'd killed followed by an outgoing call to the same number. In a very few seconds this ran up a call cost of £1.50.
