Don't trust what call centre promises

BA cancelled our flight for 5 people from Bergen Norway to Heathrow. The flight they allocated would have reached Heathrow after our connecting BA flight to Johannesburg had left. After us pointing out this error and having to change our flight from Bergen to the next day to connect to a rescheduled flight to Johannesburg we were promised by Call Centre that our PAID for seats would be reallocated. This did not happen. This has since been rectified for 3 of us but I am still working on sorting out my son and friend's seats as my husband paid for their seats and BA will only deal with him or the 2 travelers . My husband is going to enjoy being on the line for an hour to rectify BA's mistake. I cannot do it via their website as it doesn't work. Guess who isn't going to use BA again.
