Terrible SLA response for corporate products

<p>I work for a company that manufactures and builds waste water treatment centres and plants. We bought a HP Z240 workstation with additional RAM and additional graphics card for a new draughtsman. the extra RAM module didnt work since day 1 and when i logged the call with HP i was told it will take 2/3 days max for the part to reach me. It is now almost 2 weeks and i didnt even get an update from them to let me know why this is taking so long. So when i called today i was told that my call has been escalated to logistics to source the part. Just great, HP cant find their own parts, brilliant. When i asked when i could call back i was told by their agent to not call back and to let logistics do what they can. Who cares if my business is losing money, they are HP, they can do as they please. Pathetic aftersales service . </p>
