I ended up complaining to PayPal and they arranged a full refund from this organization. I have read that PayPal doesn't always do this, so I count myself fortunate. In the meantime, I notice that SafeCart is no longer on Facebook. I still marvel that they are or were able to do business in what could most kindly be described as a most unconventional way. I also wonder why there appeared not to be a specific Canadian government agency able to deal with such disgraceful corporate behaviour. Perhaps something has finally been done in the intervening time.
