Hi Helen, 

First thing we did was to ask Opel's opinion on this kind of scenario. Here was the response:

‘Many customers are coming across this issue as the infotainment systems in new cars continue to advance. It sounds like this is a phone compatibility issue, in which case I would suggest you request a copy of the list of the compatible phones with your IntelliLink system, which your Opel dealer should be able to provide. You should also check if a software upgrade is due on your phone which may resolve the problems you’re experiencing.’

If that is not the issue, then I'm not sure what to suggest as your next step. Unless the car delivered differs from that on the order specification, then I don't believe Opel will be able to do anything further for you.
