Arch Graves

So recently I was told by a friend that they were going to transfer me a large sum of linden on secondlife for a random reason. That has nothing to do with my question. But what they told me is that they bought the linden from SL and it will take 3-5 days to get to me. I can't find anyware on the SL website the option for being able to do this, and that was 6 days ago. Am I being lied to, or am I just not understanding whats going on here? any help would be greatfully appretiated. Sorry if this is the wrong forum for this.
