Just an update.
I got bored of waiting so emailed the guy in the letter I screenshot, [email protected]
Got a refund for the 5 magazines via PayPal within 30 minutes.
Was a tad miffed last Thursday as Steam announced a new updated version of the steam deck for same price as my 1
They also anounced a price reduction for mine as well
Upshot i put in a support ticket for difference in old/new price and i have 180 quid in my Steam wallet
Result
And today's email.
Seems that it's possible the magazine may get published by another company.
I suspect it will take months/years to see if that materialises by which time most people will have forgotten about needing refunding if it doesn't actually happen.
