I ordered a Dell E6420 laptop but it was a faulty refurb unit that shuts off without notice, losing my work. I sent it back to Amazon Aug 1st, 2021 and was promised a quick replacement by Aug 9th. Today, instead of getting delivery, they emailed a delayed shipment notice stating the unit will ship out Aug 19-23. In all, If I'm lucky, I might get it after nearly 23 days. Worst yet, Amazon has no customer service number to call. They offer an automated response that doesn't answer your questions or give explanations as to what happened. This not the first time I've had trouble with their delayed shipping.
