That is exactly what I replied to them, to which I was quoted a mouth full of small print and told in no uncertain terms - no authorisation from JustSim, no refund. Quote "All sales are final - No Refunds will be given"
I think people need to be aware that this is SimMarkets policy on refunds - I will certainly think twice before purchasing anything on their website again.
Unfortunately, a lot of products are only available from them so maybe I will be cutting off my nose to spite my face.
