Replaced my Kindle free of charge - great.
However they took £150 incase I didn't return the old one. Ok, not so bad.
They 'refunded' my £150 in a gift card. Not too happy about that. My bank account is now £150 down for the foreseeable future. It'll take me many months to spend that.
Even more irritating is my wife had to replace her Kindle for £50 since it got broken, and I couldn't use my gift card credit to do it. Why tf not?
And yes I know it's a first world problem. First person to point that out gets a dirty look.
