Nightmare trying to change my region and dealing with sales people!!!

Has anyone else had the same nightmare problem trying to do a simple thing like, change region. I had a Swiss subscription so got billed in CHF but I have recently moved to New Zealand and wanted to update by payment details so I can claim the GST through my business. Simple you would have thought!! NO, I had to contact Adobe, talk to salesperson that didn't speak very good English and was told I had to "cancel your Swiss subscription and then reopen a new subscription in New Zealand". Really, there's no option to just change regions and then your banking details etc. So, I cancelled and reopened a new subscription. But now, I keep getting an error message saying "this subscription will run out in 0 days - please call helpline for further advice" - when I do, I get put on hold listening to shit music that keeps cutting out and then when I do finally get through, I'm speaking to the wrong person because, I have a 'business' subscription. I then get put on hold again, listening to shit music that keeps cutting out. Why can't Adobe at least give me the option of 'for business subscriptions, please press 1 or 2 or 3, or whatever. I why do I have to keep listening to shit, cutting out music, do Adobe not have a better system. This has been going on now for 5 days trying to get this sorted. As you can tell, I'm a tad frustrated!!!!! Adobe customer service is NAFF
