More black marks for Dell

I'm still very satisfied with both of my Dell computers. But their customer service is so abysmally bad, it is unbelievable. I already told the story how I ordered one computer from Dell, they sent me two computers by mistake, and then it took me 6 weeks before I could get their logistics department to take the second computer back. And what happens now? You guessed it, Dell is sending me a reminder for the invoice for the second computer, which I have sent back over 2 weeks ago. So while before I had 2 computers and 1 invoice, now I have 1 computer and 2 invoices. Well, one invoice is paid, and I'm obviously not going to pay the second one. But I guess it'll take me another long series of e-mails and phone calls to get that mess sorted out. *Grrrrr*
