Poor Service - Online and Callcentre

I needed to change a flight booking urgently. The website would not allow me to do this as it kept popping up with error messages or crashing. I called the call centre, but their line kept cutting midway through the long process. I called 3 times without success. The nature of their call centre doesn't allow the consultants to call customers back. I had no choice but to book a completely new flight on another airline.
