Dear Credit Card Company:
I make a reservation for plane to Toronto using your credit card.
I used your credit card to hold a hotel reservation in Toronto .
Why, once I am in Toronto, do you decline my card to pay for that same hotel for “suspicious activity”, making me call you (international long distance or hotel telephone rates) to get my card released. (A hotel, that by the way, checks photoID of customers).
Surely, with all the Big Data you have available to you, and the interest rates you charge to customers, you should be able to figure this out. I did all I could to telegraph to you about my travels but write you a letter.
Annoyed customer.
