By thye way I also saved the full transcript of the call I had with the Virgin agent. In it it clearly states
'however the only free Netflix subscription for your service is the standard one. What we need to do here now is to change this premium service to standard to avoid being charge.'
'I am so sorry for that confusion but we only offer free standard and more than that you will be charge for the full amount since suddenly Netflix change there prices.
'Our package comes with Netflix standard, if you opt to get the premium then you will be charge for the full amount of the service.'
