I logged in on a site with PayPal to see how much is the shipping and didn't finalize the transaction, however in my bank it shows I have an uncompleted charge by that site through PayPal. Can't use that amount of credit on my credit card,  because it shows as reserved for that charge. There is no sign of the transaction in my PayPal transaction list and the online store thus far hasn't figured out what's going on. It should be a legitimate store and not a fraud. What's going on and how could I get it cancelled if it doesn't even show under my PayPal transactions?
