That clueless dweeb at PowerQuest got back to me over the weekend with a more intelligent response than last time.
Due to the high amount of e-mails received we are sorry for the delay in responding. In order for us to check the charges made onto your credit card, we will need for you to provide us with the credit card number. If you do not feel comfortable in e-mailing the card number then you can fax it to 801.437.4064. If you have any further questions please let us know.
Delay in responding? I don’t remember a delay. The problem last time was that the reply made no sense. But no matter.
I wrote back quoting the credit card number in question, and adding that I had no real problem quoting this in e-mail since it had been cancelled. I’ll be interested to see what happens, though I am by no means holding my breath.
