I cannot order an Uber because of MSC

MSC puts a hold for$250 on my credit card on 24/12/18, they proceed to take what was due to them on 29/12/18. We were told on the ship the hold on the our credit cards will be removed 10 days later. Now the call centre from MSC tell me it will take 21 days. It is highly frustrating and inconvenience how MSC treats customers after a cruise. Lies and beurocraric nonsense will stop me from using MSC ever again. I am very upset
