Clarry this one seems like the reverse of the auto re-lists which have been coming out of the 100/150 free when they shouldn't.

I would personally get a call-back from eBay regarding this.  The CS reps on that 'help' line are usually able to sort things out - they do not read from the standard response pages.  From what I read from other members here, email is pretty much a waste of time.

Once you point out that the listings you did should have come off the 100 free before they went anywhere near your 40 free for the month, I believe you will get a full credit for the 40x$1.50 charged for.

I always use the call-back option when I need to contact eBay - it's a lot quicker, and I've always received a positive (almost professional) handling of my query (usually re-lists coming off the promotional free).  Just make sure you ask for a reference no. for your call.
