Travelonline inefficiency costing us an MSC Cruise?

On Saturday 10 March, I attempted to book a cruise with Travelonline, on the MSC Sinfonia from Durban to Venice on 20 April. I only received an email reservation at 15:20 on Monday 12 March, which I accepted immediately and asked for the required documentation to finalise payment by credit card. In response, I received an email to say the reservation had been cancelled at 15:00, promising a new reservation by Tuesday 12 March. Note: It had only been received at 15:20! As I was in surgery on Tuesday, I asked for an urgent reservation and asked certain questions. This was followed up by telephone calls and more emails to stress the urgency, which seem to have confused the consultant completely. On Wednesday 14 March at 13:10, I sent another email, stressing the urgency of receiving a new reservation and the required documentation for credit card payment. At 17:30 on Wednesday (apparently sent at 16:19) I received a nebulous reply to my wife's email on Tuesday, stating she will "see if a cabin is available." We have persuaded friends to join us. They have booked and paid, and we still have no reservation!

Will the inefficiency cost us the cruise and tarnish MSC's image?
