The way they automatically add on a “tip” for the company is deceitful. It is possible to remove it (multiple steps to do this though) but they’re clearly relying on the fact is not very obvious that they’re adding this on. I can’t imagine anyone would opt in to tip a company so it explains why they’ve gone to the trouble of making it the way it is. I can see by the recent reviews that it’s catching a lot of people out. They need to remove this ASAP to avoid reputational damage. I have already requested a refund of the tip (not the donation). As far as I know, they already take a cut of the donations so asking for more money is not good.
