We had our first cruise last week. When we received our account on the last day I noticed that it was showing a $200 charge for the stroller that we used. I had returned the stroller the afternoon before, so I called guest services and they said that they would reverse the charge. I have just checked my credit card online and they have still charged the full amount. Is there a phone number I can call to try and get this sorted? I thought it was strange that they did not give me any paperwork for borrowing or returning the stroller.
