Travel Restrictions Not Mentioned on Barclays Website

We've had the Travel Pack Plus (and whatever it was called before it changed in 2015) for many years through our Barclays Premier Account. This year was the first time we needed to use it. Our daughter (aged 20), travelling with us and who lives at home fell gravely ill whilst on holiday in Crete. She was put in a coma on life support in the ICU for 10 days. We telephoned the helpline number for advice on getting her home and we were informed that because she wasn't in full time education this year she wasn't covered. They wouldn't even help us with what to do, who to contact or any guidance whatsoever. Our daughter recovered well and was able to fly home to a UK hospital after 2 weeks - we had to arrange the repatriation ourselves and with the help of friends in the UK during what was the most terrifying ordeal of our lives. The bill for the Air Ambulance Plane was £22,000. Before we had our Barclays Premier Account we would always buy travel insurance for specific trips. Having this Barclays travel pack gave us a very false sense of security. I have just looked on the Barclays website for the Travel Pack Plus and it doesn't mention anywhere that I can find about these restrictions. It says that it will cover the whole family if they are travelling with us. About 3 screens in you find the Terms & Conditions and even then the Key Exclusions don't mention anything about children ages or current education situations. I would be interested to hear how many others have been affected by this. I have telephoned Barclays and logged a complaint about the way this is sold.
