a bunch of *********** staff

My sons school iPad was booked in for repairs, 3 months down the line we have not yet received the iPad or feedback as to where it is, when we call its either someone will call us back and they never DO. This afternoon we called again and was told that the manager is not inn, they will send him a message and call us back with in an hour, its already at night and no one has bothered to call. It's been a 3 months struggle for my son to do his school work because most of the work is done from the iPad. Can we please have feedback.
