Godaddy sent me an email notification but already billed my visa

has anyone experienced this? they have auto-renewal on by default? is it even legal to have that option on by default? how do i get my 10.88USD back? it is not much but i am totally pissed off by this. i personally think that there are better ways of making money than doing this.

they sent me an email confirmation but they already deducted money from my account. i never got the chance to confirm anything. they just deducted it right away.
