Please could I suggest that the best way to resolve this one is to write to OAT directly and not to post on pprune – this really is an inappropriate way to get it sorted. It may very well be an admin error. Mark it for the personal attention of the Managing Director, Anthony Petteford, if necessary.
I assure you that we take customer satisfaction very seriously these days, whatever may have happened in the past. The law has changed on NVQ and it may be that your friend was genuinely eligible and you were not because of some time difference or some small print.
If you have a genuine case, it will be taken seriously. Oxford does not give its customers the brush-off.
