I had my car smashed to pieces and my mobile phone stolen (fell out of my bag and didn't realise.)
They said to me they would pass the information to a specialist team to track the phone (incident happened within the last hour so may have been possible)
I called up after a few hours to find they closed the case and never bothered to attempt to track it.
I know I'm just a statistic and I wasn't holding much hope of getting back but they were the ones to say they would at least attempt to track it.
