I just had a disquieting experience with a Vertical Doors supplier in Corona, CA.
After having asked and been answered some practical questions regarding vertical doors, sometimes called Lambo doors, for my Camaro, the fellah wanted my phone number to discuss it further. I told him, at that point, how I had already had done that after having ordered the doors on line and paid, I thought, by credit card. I told him how I had been quizzed earlier for all sorts of personal information that the salesman for Vertical Doors told me was requisite to purchase their product. Of course, at that time, I refused, and I told the fellah on the phone how suspicious that all seemed. :(
Now, I said, "Here, that is why I've brought my checkbook." He replied, "No, we don't accept checks." Miffed though I was, I told him that I'd even write a check and wait till he is happy that it had cleared. He refused. Only the credit card with the full set of information would do.
At that point, it was clear to me that a scam was in progress. I immediately left.
