Yeah, much beetter to be safe than sorry.

A few years ago I had contacted the Dell Support Team about an issue I was having with my order, and they called me back and had asked me to give them my card details so that they could cancel and make the payment again. I wasn't comfortable with that so asked if we could do it another way. I was a bit nervous?, about asking but they didn't think it was weird at all and were very accommodating.
