I do agree it is pretty much gambling as your risking your hard earned cash for an item you may not win & receive. It can't really be argued that its not gambling as to be seen any different they would simply have to not charge the premium rate phone call cost to those that didn't win.
They do seem to be trying a few different sales techniques and no doubt this format will make them a lot of money, I just hope they don't keep doing it.
It would be interesting to know if they required a gambling licence for it, I think its regulated by the Gambling Commission who grant/revoke the licenses.
Could anybody 100% confirm that they did charge the premium rate phone call cost even to those that didn't win an item?
They admitted in a recent ASA Upheld complaint that in similar circumstances they do generate some income from situations like this.
