Horrible Customer Service. DO NOT use themI I took this cruise back in May 2018. After the cruise I bought a snack and drink from the little shop onsite. After swiping my card, they claimed their credit card machine wasn't working so I paid cash. When I got home I see my credit card was in fact charged after paying cash. I've been trying to get them to refund the charge since then and they keep saying it was voided. I sent them a screenshot showing the charge, now they are asking me to send them my ENTIRE bank statement. I am about to file a complaint with BBB Canada. I will never use this place again - so unprofessional!
