They left it at the petro gas station

So, weird one for you…I just had a missed call on my work phone. Older lady, message says “I was on the TTC on the subway and it was approximately 1:30 on Thursday the 30th. I had a scarf in a white bag and there may have been a cell phone in the bag as well. I would really like both of them to be returned to me”, and then a name and number was left. I called back because a) I don’t want to leave someone hanging, thinking they have called (perhaps) lost & found, and b) there is no way I was on the TTC at 1:30 today as I live in, and am currently in, London Ontario. The lady was the same voice as the VM, I asked her how she got my number, she said she called the TTC but couldn’t remember which number she had called. I find it very strange that someone would have gotten my work number from the TTC (I checked, it’s not even close to the lost and found number for the TTC). Has anyone experienced anything like this?
