I was disappointed because I ordered 2 pcs of Lenovo ThinkCentre Premium High Performance M91P Desktop Computer but  I received only 1 unit  and from the 1 unit that I received  the hard disk doen't work so I have to replaced it with a new news one and the wLAN that was together with the unit its cd driver is broken. I hope you can double check the quantityof my order and on the 1 unit I received if you can provide me the replacement of the 1 TB hard disk which is supposedly with the unit. Can you send me also the other unit of Lenovo ThinkCentre Premium High Performance M91P Desktop Computer or I'll just take back the money I paid for the other unit. Thank you.
