That's not true at all. Try getting a refund in Europe during the summer. Or Christmas. Or on the weekend. Or any random saint's holiday. Or any time the person you need to talk to decides to take a 2 week vacation.
If you think there's a country where refunds are easy, name it.
Also that dude didn't even name the country. It doesn't even make sense. How would businesses even make money if you could just get a refund on anything in 2 weeks.
He's not refunding an apple in 2 weeks. What about a sandwich? Some used socks? Underwear? You could just never pay for anything, returning it twice a month if you wanted to.
Other exemptions are found in the link as well. Think train tickets, groceries and digital content.
When you're getting the actual money back could vary with online purchases, of course. Usually it's the bank that is processing the transfer taking their sweet ass time and not the refund issuer, but I digress. Yay for consumer rights!
