Incredible *******ion

So Incredible Connection has made yet another pricing error on their site. I bought 4 X Graphics Cards and now they have sent me an email saying I will be refunded due to the fact they made a pricing error. Now they tell me I will only be refunded in 7-10 working days! Why must I wait that long to get my money back for an error that they made!?!?!? I want it back now!
