Best Buy review: technical support

Brought computer for normal assistance, clean up. Had to make a second visit because lost all my files and my access to outlook and Microsoft office. Called on phone for assistance, limited assistance. Told to go back a third time to store. The phone continually rings and rings. Appointment availability is extremely limited. I think I will contact NYS Attorney General for assistance because we brought product at Best Buy and have contract. More problems because cannot get into my documents, etc. Thank you.
