When my dad tries to buy things on iTunes my credit card is charged

[beansmum]

Why is this happening and how can we stop it? I have used his computer to access iTunes a couple of times but shouldn't it know the difference?

Remove your card details drom itunes.

how?

And if I do that how will I buy anything?

I dont know how sorry, but I would imagine if you close your account, and re-register if will be fine as long as you dont use your dads pc to buy.

I don't use Itunes, but when you used your dad's computer did you have to log on? if so is it remembering the logon and logging him onto your account?

If that applies you need to log OFF on your dads computer and carefully log him on as himself.

I've called him and asked him to sign out and in again, hope that works.
