My name is Glenn. I am top-exec in a global bank here in Asia. I have an offer for you that will greatly benefit us both. A customer of ours died 10-years ago and left unclaimed, dormant funds in our bank. If we work together, we can easily claim this money because of my position and your surname. If you wish, I can send you more details.
