I learnt the other day that they are just a reseller for CRB in scotland. So when one of my friends at another school wanted to suggest improvements, they advised him that "they would pass it on"
The epos system is always the blame factor, but in reality it relies on the the account balance holder in your case PP. The trust-e till that we have has an override function in case of such circumstances.. talk about a plan!
My only issue is that it is not Cunninghams.. theyy just sell it for a scottish company CRB.. so when we had issues we had to chase various other parties...
