As this is your first post, welcome to the Pure Planet community. When you post here you are talking to your fellow customers, not directly to Pure Planet. But those fellow customers will do what they can to help.
Try resolving this by going to the three little bars top right corner of the app, click on Help, then choose Wattbot and put Amazon voucher in the question box.
If that doesn't help, come back here and ask again - there'll be lots of people willing to help. Or search 'Amazon' in the community and see what others have been told when they asked this question...
Hope that helps, and you get your voucher
