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.
I'm tempted to ask why you would want to put your payment up - remember that your direct debit is reviewed every six months - but if you insist, the next question is how you have been trying to get Pure Planet to change it... So far as I know, the only way is to go to the app and click on the three little bars top right, choose Help, then Wattbot, put'message the team'in the subject line and then explain what you want them to do. They promise to get back to you within two working days.
Just be sure you want to do it!
