Hello,
AP staff have to cancel stamps, part of their job. They have been negligent in the performance of their duties. Start with them. I dont bother, but an uncancelled stamp is still fine to use IMO. I would not try to sneak through one that has though. It seems to me a bit like a price error in a supermarket, they set the price so they can take the loss.
