. I took my credit card statement showing the charges, and my credit card, and my booking confirmation to prove I had paid, and they promised there would be no more problems - but yet went ahead and charged me the second and third times. No apologies, no corrections.
Gees.. amazing that you;d pack your credit card statement to take on a cruise. Have to admit I've never thought of packing it
Curious what credit card company it was that wouldn't challenge the charges. That is normal routine business practice with every company I've ever dealt with.
Even back when I was the vendor we were required to respond with signed and approved charge slips for any contested charge within 7 days or the charges were reversed... with Visa, MC, and Am Ex..... that I dealt with.
