I suspect you don't have any comeback, if you read the small print! I bought a Vodafone genuine PAYG dongle about 3 months ago, but have now read the credit will only last 30 days! According to the small print they have a loop hole. By the way speeds have been going down with the explosion of dongles. I believe the new Iphone is having problems in some areas due to traffic on the 3G network.
