On, or about July 8, 2020, I was contacted by a Donovan Murphy, a cruise specialist with Viking Cruises. I had previously expressed an interest in the "Paris to Normandy" cruise, but did not go further due to the COVID shutdowns in the US and Europe. Mr. Donovan basically promised me numerous enhancements and upgrades if I booked this cruise. I booked the cruise for two people and set the cruise date in April, 2021. In December, 2020, I paid the FINAL payment on this cruise ($10, 202.88). In February, 2021, as I expected, Viking cancelled the cruise scheduled for April, 2021, due to existing COVID restrictions in France. I was advised that I would receive a voucher worth 125% of my earlier payment. Unfortunately, my guest then decided that she no longer wanted to go on the cruise. I was advised by Mr. Murphy that she needed to send Viking an email voluntarily returning her share of the voucher to me. She did this, as requested. Now begins the problem! I received another invoice from Viking on June 17, 2021 stating that I now owed another $3, 169.20!! I have contacted numerous officials with Viking hoping to resolve this issue, but to no avail. One cruise specialist, Lauren Deger, encouraged me to pay the extra fee. To make matters worse she said if I did happen to find another person I would have to pay an additional $5, 267! Now the cost of this cruise is up to $18, 639.08!!! I then requested to just cancel the cruise and I would take my original amount of $10, 202.88, and book a cruise with a company who treated their customers better than Viking. I was then told that I could not receive a refund if I cancelled, as Viking only issued vouchers. What a wonderful policy for Viking River Cruises!! On a personal note, prior to this incident, I had heard nothing but good reports about Viking and their cruises. This was going to be the trip of a lifetime for me and now I have no interest in even traveling abroad.
