Not a great first impression - overcharged on order

Just ordered a kit plus some extras.

Cart showed 20% discount and free camera. Clicked all the way through and paid - same price quoted throughout.

Received an email showing total charged as the full amount, also checked my credit card which shows a pending transaction at full amount.

On the plus side, the wait time for customer support was fast, the person was friendly and helpful and apparently the order amount has been amended. But the pending amount hasn't updated on my CC, and no email update received.

Not a good first impression, and pretty awful that their web store system will claim it is charging one amount, but actually take a different amount. Does not instil confidence in the company when they cannot get the basics right. If the customer service had been poor I'd have cancelled, but as it is I'll have a look at their kit, but unless it is a great experience I'm already thinking of using the 60day returns.
