Charge backs arent always bad, thats for sure.
I ordered some 4k movies recently from sunshine records in Canada.
I qualified for free shipping.
Apparently I wasnt supposed to because im in the Yukon, so after my package had already shipped, they said they would need to charge me an extra $54.
They said if I didnt want that, I could arrange a return.
I threatened them with a charge back straight away. I am not taking my time to arrange a return and if you charge the extra shipping, Ill do a charge back immediately.
They relented the same day with a long apology that once the issue made it to management, it was an absurd proposition by the employee.
I dont think Id ever risk my PSN account though, Id have to take my lumps if I got screwed.
