I have requested a refund after taking legal advice in the UK, might need a CRN ( crime reference number ) that way it escalates, also intend to take my single PSU to Trading standards who do safety checks on consumer kit in the UK to see if its legal
In the UK, they're legally obliged to give a full refund (so no admin costs etc) within 7 days as per the Distance Selling Act and the Consumer Protection Act.
You can get a full refund for upto 7 days AFTER you have received the goods (yes, you have to send them back obviously).
IIRC BFL offer refunds with 30-45 days (which would be illegal in the UK as is their 'All sales are final' policy).
