Had an issue with my hard drive and I called Dell with a quick question about it and their response was "your hd failed, would you like to purchase a new one through us". I am in school for cyber-sec so I knew that not to be true, after continuously working on my computer I discovered the issue and my computer is working without purchasing a new hd. The technicians do not have much knowledge except for searching google.
Also when you call it sounds like a bunch of people shoved in a room having a party, you can barely hear the person you are speaking with on the phone.
