DD, continuous payment, whatever it's called - I just meant taking a regular amount each month. Can't see why that can't be done by PCW, I've got several companies that take a monthly payment by CC.
What really pisses me off is the total inflexibility of not getting a deal or discount. The sim card was a minor issue, but as the advertised deal was unavailable there was no offer to compensate me by reducing the price or throwing in something else gratis. I had to ask if they would consider it and the response was an outright NO. You'd have thought that in order to secure a £600 sale they would have offered some sort of sweetener, especially if asked.
