Skype's behaviour in its automatic recharge is unethical. It is a way of taking money without the consumer's approval. This has happened a few times to me, but now I'm on to this. Each time you purchase credit Skype automatically renables the automatic charge, so each time you buy credit you have to disenable the automatic recharge afterward. It's a pain to do this each time when you know that you don't want this, but this is the unethical way that the company chooses to operate.
