I'll confirm I reported this on the 4th
I reported this, but I didn't post it to the media as I thought it was somewhat irresponsible to do so and once fixed it is kind of a moot point really.
It was fixed by the end of Monday 11th and my initial phone call was.... 5pm-ish Monday 4th February. I asked to speak to a manager, they rang me back at 7pm. Midday Tuesday another manager rang for permission to give my details to someone else. Someone else rang me on Wednesday, I emailed them screenshots and a description around 4.20pm Wednesday. Tuesday 12th had a voicemail from the same someone else to check the problem was solved.
Without doubt the hardest part was explaining that this wasn't just a case of someone else using my computer and me needing to clear my cache.
