My experience of Dell support:

1 bad work-related experience out of innumerable calls over many years at 3 different employers.

3 bad 'home purchaser' experiences out of 3 calls related to one purchase including the immortal phrase "you were misled" which basically meant "the person who dealt with your order but refused to answer your calls or emails after failing to do what he promised to do shouldn't have promised that anyway and didn't get authorisation as he claimed".

What was I promised? That my personal purchase would be delivered to my work address at the same time as the 4 laptops and 3 desktops I had ordered for work that morning. Thankfully my account manager for work was an absolute angel and sorted it out for me but even she was surprised when I asked her again 2 weeks after the original request if she could help. She had been assured after the first time that it had all been resolved and the delivery redirected as promised.

Paris 'cos she'd know how to keep the customers happy EVERY time.
