REPLY:

No doubt your call was in his log, the question is how did it get
there? While I love Super Check Partial, I think it might be the
culprit sometimes. When signals are weak and someone has a call
similar to yours, or which is a partial to your call, it's easy to
become convinced that it's your call and that's what goes into the
log. 

What's the answer? Don't know, it's going to happen so just  be
careful.
