I have had an issue wiith so called Smart Pricing which I spotted because 4 nights in the height of summer were booked at just above my minimum price. I always set the price for summer dates automatically so I am certain that a dodgy algorithim has changed my manual settings to "Smart Pricing" and then sold the dates at a ridiculous discount. I've contacted customer service but been fobbed off with a claim that the Smart Pricing Team have "confirmed that smart pricing was set up for these dates." I just don't believe this is correct but have no way of proving it. It feels a bit like the scenario with the Post Office staff in UK where no one accepted that the software was wrong.
