A rental request that has not yet been confirmed by the Lender, you can not cancel, but simply delete. This is free of charge and since no money has been received yet, no refund is necessary or the reserved amount on your credit card will be released. Cancellation refers to rental requests that have already been confirmed by the Lender. You do this by clicking on the button Cancel in the corresponding rental request. Cancellation costs you a flat rate of 20%, the rest will be transferred back to your account. However, other Myfundus users can see how often you have already cancelled rentals (via the so-called cancellation rate). By the way, you can cancel until shortly before the start of the rental period, namely until 23:55 the day before the start of the rental period at the latest. After that, the entire rental amount is due.
