The Channel 4 Dispatches programme just shows how a successful industry works.
In spite of the dominance of foreign handset and network manufacturers, the UK networks have developed in such a way as to influence the mobile business strategy of nearly every major market.
However, the cash back problem is the epiphany of the something for nothing culture that was encouraged by the networks, but not underwritten by them.
Also whilst data, SMS and roaming charges counters their declining call revenues, it is causing massive problems for many people unaware that what is free in the UK could cost hundreds of pounds overseas.
If Visa & Mastercard can contact customers of unusual spending patterns, the networks could do the same, and save the sanity of many of their customers.
