quite possibly, it would be nice if you got an alert to negs.  I had one a few months ago,  I have heaps of sales, but don't watch the feedback so it slipped through for a couple of weeks.   Similiar situation actually size of the item was in the description, but they thought it was small for the dollars.  I ignored it,  no point calling them a turkey in reply.   I don't believe in the old saying the customer is always right,  but it reflects badly on you if you call them an idiot.
