All you have to do is say they refuse to work with you and you can get
the amount charged back to your card. It's simple.

Nope. They didn't refuse. They were very cooperative just incompetent

in two weeks, the rest dribbled. Do you suppose that it was because they
were Dell?

I believe he was referring to the credit card company, not the vendor.
