Very very bad service British Airways.

I am frustrated, angry and very sad. On the 24th of december we were supposed to fly to Capetown with British Airways to be with my daughter at Christmas. I haven't seen her in two years. So we were very supprised that at the check in at Amsterdam Schiphol we were told that they couldn't check us in because of a failure in the ticketnumbers. They couldn't do anything for us and we had to contact British Airways ourself. It took an hour to get somebody on the phone and then they couldn't fix it on time so we mist the flight to London and the fligt to Capetown! No Christmas with my daughter. We went home and again i was a few hours on the phone with British airways. Finally at 21.00 in the evening they managed to book a flight on the 26th. Because i didn't get a confirmation by mail next morning i called again and they told us that there was no e-ticket made for us! If we would book a ticket on the 26th we had to pay the difference in price. I said that i didn't accept that because it was their fold and i was so sick of it all that i wanted to cancel the whole ticket and i wanted a full refund. And than they told us that this wasn't possible because we were a no-show on the 24th!! A no- show?! We were at the airport and they couldn't check us in because of a mistake of BA! Long story short, after in total more than 5 hours on the phone with BA they still couldn't fix the problem and finally they offered us a full refund. I asked for a confirmation but now we are a week further and i still didn't get a confirmation. We made a lot of telephone costs, we had to do a new pcr test and we missed Christmas. Finally we were very lucky to book a new ticket with KLM and so a few days later i was with my daughter. We are very dissapointed in British Airways. The service is very bad and i don't believe that we wil get our money back. Next time for us no British Airways!
