MSC Cruises are pretty USELESS!

I have received such bad service from MSC to the point that a member of our group does not want to travel anymore because you are making the trip so miserable prior to even travelling on the 24th Jan 2019. Earlier this year I made a booking for 5 families, 4 of the 5 families were placed together on one deck. In November I called to get a QUOTE on what it would cost to add a toddler to one of the bookings and MSC decided to change rooms with no real confirmation from the traveler and one of the families was now moved away from the rest of the group. Trying to resolve anything with your contact centre is pretty useless as no one can help and no can provide feedback. We were fighting a losing battle trying to get the original room back and we gave up. Then with the same booking it was requested to dine on the first seating for the evening, that was another battle we were fighting. Eventually all families was bumped down to second seating (when I last spoke to an agent) as we are a group. Yesterday we all get our etickets and guess what, this particular booking is the only booking on second seating and everyone else is on first. This doesnt make sense especially when all our bookings are linked. You guys are unhelpful. You guys are useless and making the experience of this particular traveller very miserable. And apparently no one can do nothing. The particular query I'? referring to is reference number ********** 0. I bet that I won't receive feedback on this query because your customer service sucks. I can refer you to institutions that offer customer service courses!
