Still no satisfaction! Last Friday morning, I called Apple to complain about the service centre's non-responsiveness. The agent agreed that 6 weeks was a very long time for a latch repair and said she was emailing the centre's management to ask them to contact me. 5pm Monday and still no word, so I called Brilliant Ascent Development (BAD) and miraculously reached a human operator for the first time in many attempts.
She checked the records and told me that some part had arrived on the 12th. I pointed out that today is the 16th and asked why it had taken so bloody long in the first place. She sounded annoyed and gave some explanation about the laptop being at some warehouse and not at their centre. She said that they will call me in "about two days" to "confirm the collection date."
This is so ridiculous. BAD needs to change its name to AWFUL. I suggest that you avoid this place the next time you need your Apple hardware serviced.
