On and off switch in buying energy with tlrpg

I would like to suggest ang on and off switch in making transactions using tlrpg. I have encountered an unintentional purchase of energy. This is so frustrating. There should be a confirmatory button or a code to be sent via email when making a purchase using tlrgp. I lost a total of 50 tlrpg for this flaw in buying energy. I hope you will act on this. A refund will be highly appreciated.
