You shouldn't require the services of a lawyer in order to get the points.

What is more worrying is that they seem to admit there was a "problem" with the Avios 10x referral even for people who were 100% eligible and noone has got their bonus points automatically, requiring people to make phone calls in order to claim them.

If it was just a handful of people, ok, computer error.

Since it seems to have happened to EVERYONE, i think it's really dodgy and not the behaviour I would expect from one of the countries oldest financial institutions.
