After having money stolen from my account with no warning was refused a refund.
I urge others coming here to report Productionbase to Action Fraud https://www.actionfraud.police.uk as this will be the only way to stop their antics and protect others in future. Pursue them for a refund as the wording 'this is our company policy' actually means nothing in law and is just used to fob you off.
Also - be aware if you do manage to find the way through the layers of pages on the website to the hidden cancellation page, they will not send the promised confirming email - so you would not have proof of cancelling when following up.
The guy who founded this site was a good guy but he sold it to a bunch of scammers long ago.
