You have taken away my authority to refund during the campaign. You must charge a fee to someone who has lost the refund button during the campaign. Also, then you did not inform me that there was any commission. Your bike price includes 5% Indiegogo commission, 3% credit card fee, and 2% transfer fee. All this imposes an unfair fee on me. If I have kept the purchase, it is the fee that you have to charge anyway.
It is not my responsibility for not being refunded during the campaign period. I will sue you for your one-sided fees. This is wholly caused by you.
Please contact me if you have any unfair refund fees. Let's act with me. They took their responsibility to consumers. firstname.lastname@example.org
