I just ordered an XPS desktop by Dell.com Canada, and I chose to pay by PayPal. However after I submit the order, I got an e-mail from Dell which said that an issue is encountered with my original payment and the transaction could not be processed. I checked my PayPal but it shows that the payment is still pending now and I would only be charged when Dell completes my order. I am confused, did Dell try to charge from PayPal and fail, or Dell has not begun to process my order? If there's indeed some problem with the transaction, who should I contact? PayPal or my bank?
