Can someone help me translate the following message.  I got this on my machine the other day, my French has been improving but this just sounds like a jumble of nonsense to me.  I even asked my friend who double majored in physics and french in college and he was stumped between bonjour and technique so he didn't do much better then me.  Maybe a native speaker can do better?

I was able to extract the phone number but I can't really make out what it is regarding.
