I had a shipment arrive in Pearson Airport in Toronto. When I arrived at the cargo office for the United agent at this airport I was ready with cash in my hand to pay the charges. I was told that they no longer accept cash but I could only pay with Visa (no debit Mastercard or American Express). I do not have a Visa credit card so I had a big problem. After considerable time arguing with United they still would not budge so I was about to call in the police to demand that they release my property when another customer offered to pay it in exchange for the cash. United is an awful airline and their unfriendly service should be a warning to anyone that wishes to do business with this airline.
