Amsys

If I could review without giving any stars, I would.

Apple sent me to them, something I later regretted deeply.
At first they seem nice, but when you get back to them, take your device, you discover that they've completely wiped clean a full back up drive, and denying it ever happened!
I've had to waste my time and money to get what I could back from a back up lab. Still all the files recovered are in a mess, which leaves me with damage that effects me greatly for years to come (as I am a designer with many important files I created now either corrupted, gone or in a complete and utter mess).
Of course nor them or Apple saw anything wrong until I showed them proof.

They're horrible, stubborn, and whoever they sent to deal with my complaint tried to make me feel guilty by personalizing a professional complaint.

Avoid at all costs. It's not worth it.
