Total disregard for customer rights!

booked for my parents to go on a cruise with MSC. booking done via onestop. MSC cancelled the trip at the time when my parents were in a position to travel, MSC cannot guarantee when travel will resume and my parents are no longer in a position to travel due to health reasons. upon requesting a refund, ONE STOP distances themselves and expect you as the client to communicate with MSC, they tell you that there is nothing they can do!!! most pathetic unhelpful company. They will tell you that they will type a mail and you must "act" like its coming from you! I refused to be dishonest and then was left to fight this battle on my own.
