What? Unilaterally refunding a purchase I made years ago isn't "bad customer service". It's just a company being shitty and not caring. I am the party that acted in good faith and purchased the content! What are you even talking about?
Companies don't like refunding either in all fairness. And your phrasing makes it sound like this happens to you regularly.
I don't think "refund" is the best use of word here. That's usually a customer returning a product. And a company with bad refund policies tends to have bad customer service.
