Update.
Those generous people at IC have taken several days but have now grudgingly agreed to extend the membership from February to September - I requested October but that was too much for them. They aren't prepared to give me a full year on the weekend cert either - it just starts with the original expiration date - whatever that was.
No explanation provided to my question as to why this wasn't escallated when I asked several times and this is the total goodwill gesture as a result of the above palaver. That is to agree to extend the membership until they sent the pack to a completely different address.
It's immaterial anyway because we still haven't got the portfolio because they gave it to someone else. It says so on the tracking.
