Been trying to speak to an Exec Club rep to amend an Avios booking, which can't be done online. Lowly Blue member and have been on hold for most of the day, each call taking an hour or so before I booted out of their phone system. Also sent direct messages via Twitter and Facebook. No reply other than autobot asking me to confirm booking ref, etc, which I have done. Never, ever been this frustrated trying to speak to customer services. Simply shocked at how bad it is.
