lucky015:Geektastic: Can I do that if it was a Visa Debit card rather than Visa credit card?
Cant hurt to try.
The problem is that the forms that you have to fill, in take quite a while to fill in. I think it would be easier for you to get dell to sort it out. I had a problem with dells service a few months ago, and eventually I did get the issue sorted. But I guess if you are running out of time to get the chargeback from the cc company, you should at least start the process.
This may help too of you are trying to contact their NZ office http://www.consumerblogs.org.nz/tech/2009/10/ding-dong-dell.html
