MSC Cruises review: Customer service

I made a booking for 12 cabins and was trying to add drink packages. The concierge who I originally booked the cruise with had left the company and I spoke with a rep named christy who replaced her. She sounded frustrated and angry even before I could give her any details. She did not help me and just told me to call another number because she did not make the original booking.

If you get her on the phone hang up and call again so get someone else. She has given me such a bad impression of the cruise even before I go on it
