Paypal - grrrr
I made what was effectively a charitable donation; they used paypal. I ticked the box saying that I did not want to create a paypal account (I read their nightmareish T&Cs years ago). The next thing that I knew I received email from Paypal telling me how to update my account settings. I phoned them, they lied to me; gave me an email address to complain to that did not work.
They are an unscrupulous bunch of crooks who have no intention of operating in a truthful manner. I will now never have anything to do with any organisation that only accepts payment via that bunch of bandits.
