Cannot watch rental movies on iphone 3gs since downloading OS6

Question

Since downloading 0S6 on an iphone 3gs, I get the message "Cannot Open" for two rental movies, one of which I had watched half of and one which I had not watched at all. The time is now ticking away until expiry on both of them and I'm unable to watch them. I've tried a reset but that didn't work.
I have rung up Apple UK twice and got two different operators, one in the UK and then one in the USA. Both seemed very isolated with no contact with other Apple Mac staff except through computer. One told me to contact iTunes support online (he gave me an url and then realized it was the American url and not for the UK) and the other gave me the same url and told me to contact iphone support online.
Both times I was left waiting for an inordinately long length of time when I suspect the operators were dealing with other calls. In fact, I got the impression, rightly  or wrongly, that I was dealing with people who were working from their own homes with minimal training and support and who were being paid for the number of calls they took and, if  there was a call like me which didn't come up with a solution on the computer screen, they went on to other calls and left me hanging.
I did manage to find the Apple UK support page on my own but when I tried to contact them the error message "Service Unavailable - DNS failure. The server is temporarily unable to service your request. Please try again later. Reference #11.7f2645f.1348163355.65fe47"

I haven't had to contact Apple UK for a year or so but I've never had such an awful, waste of time experience before with people who did not seemed at all trained or given the facilities to handle calls. Can somebody please help me on this or give me an email address for Apple Support UK?

Answer 1

I believe the issue is that you have to be connected to the Internet (the iTunes Store) when you play the movie. I'm not sure if that's just when you initially start the movie or not. This is necessary, I'm assuming, to keep tabs on their time limits for viewing the movie once it's started. You could go to iTunes Store and scroll to the bottom and click on Terms of Use. It's all spelled out there under Rentals.
