Okay, I just thought I'd update this thread.
To anyone else who is having problems with the MAC website, it IS THEIR problem.
I can get on any website apart from companies of those related to MAC, including Clinique, Estee Lauder etc.. And I've rang my ISP and all sorts to ensure there is not a problem on my end.
Problem is, I've now rang MAC 3 times over the past two weeks and they refuse to admit there has been a problem for some people. I now know of a few girls (and guys!) around the world having issues. All I have been asked is if there is anything I'd like to mail order.. Erm.. how can I when I don't know what you're actually selling at the moment?
I really am at a loss.
If anyone can offer me an insight on who to contact that would be great. Don't get me wrong, the MAC team have been great in the past but I'm becoming increasingly frustrated! Rant over.
