I placed an order with this website for an item which was displayed as £19.99 with free delivery. I received an invoice for GBP 19.99 with free delivery.
My credit card was actually charged USD 27.80 which even at interbank rates is about £23.
The website didn't given any indication that this would happen, or allow me to select the currency I would be charged in.
I contacted the company, they say:
"The charge is the bank handling fee, but we only received 19.99" and refuse to do anything to rectify the situation or allow my to cancel the order.
