Problem with online store purchase

I just tried buying the Bonus Mission Pack in the online store

When I got to the purchase page then transaction timed out saying could not connect to the transaction server

So I clicked purchase again & it said timed out again

I then looked at my account and it said the bonus miission pack had been added

Two things concern me :

1) I have read that people had their accounts locked when trying to buy storage panes when a similiar thing happened

2) Could I have been charged twice

LMK if you have experiened this & what happened

regards

If you do happen to get banned or charged twice, support will be able to sort it out. Check your bank account to see if you got charged twice. Nothing to get too worried about, though.

My NCsoft account is showing 1 purchase in billing history BUT lists 2 serial codes as having been added - I only received one email though listing the first serial code issued

I am hoping the software was intelligent enough to realise not to charge me a second time even though it created a seconf access key - which I cannot actually use as most of the digits are crossed out for security (you only see the full key in the email they send you)
