I called up Flight Centre back on the 22nd June and followed up with an email to ask for a contact that was working the following day so i could email an urgent flight request through on the weekend.
Well today I finally got a response (31 JULY) which I found amusing because of the delay and what it said..
Just writing to follow up and see if you managed to secure flights to London. I just found your email and apologise for not being able to get back to you sooner..
Good thing i didn’t wait around and booked them elsewhere or I wouldn’t have been in the UK for the last 2 weeks 🙂
