Firstly, I can confirm you did *not* receive the reward. The system spun for it, but you weren't credited with it.
Secondly, I know I've said this to you before, but I need to say it again. Without an output log, there is nothing we can learn from this. All we can do is confirm that it didn't happen.
Should the case be that you haven't restarted your client whatsoever since the end of that match, an output log is still needed. Should you have restarted your client since that time, there is no information we can get from this unfortunately.
