took my MacBook air to fix usb port and get bigger space on it
the checked it sent me email with what i have to change
they forgot to fix what i asked for

and when i collect it they informed me the fixed the usb and i came home it was not fixed
the forgot about increasing the storege space of the MacBook
the one thing that wan ted to do is change the battery that still worming and might not work in future as it was the most expensive part moreover they dot have it in stock have to wait for 14 days to get it and its not for sure
very bad service
