Cancelling Vigin Media and partner signing up - Fraud?

Although Sky and not Virgin, a friend had Sky TV at home in the Mrs name, and Sky TV in their holiday home in the Mr name ( but same surname)...both out of any minimum term, new customer promotion at the time was a 32" Samsung TV , he said they were going to cancel both, then re-order as 'new customers' but the Mr at home, and the Mrs at the holiday home, I was very sceptical , and said surely Sky wouldn't go for something so obviously contrived, but I was wrong , they got 2 TV's out of them effectively for 'free' ( as well as new set top boxes) and what's more , they arranged it with one of those Sky stalls you see in shopping centres, the 'salesman' probably on commission couldn't care less, and signed both addresses up after the 'cancellations' we're on file

As far as the OP and Virgin, I recon the customer service rep was probably going off script a little, or if 'policy' , it's in unenforceable, people must cancel Virgin every day, and 'new' customers 'takeover' existing Virgin connections every day, I doubt if they even care if the outgoing and incoming customers are related.
What if it's a genuine home mover but both the outgoing and incoming people are called 'Smith' , 'Jones' or 'White' or any other quite common surnames, and in the OP's case the surnames are not even the same .
The only downside I can see is there may be a short period of no service between the cancellation of the existing service, and an install date of the 'new' service, obviously if a retention deal is equivalent to new customer deal, why bother , but if it isn't, then why not ?
