You may have received a payment notification from your bank for a purchase made at the FELFEL fridge without using it. Don't panic, there can be a reasonable explanation!
Possible explanation 1: Weekly billing method
If you've chosen the weekly billing method for your FELFEL account, you'll notice that your purchases are charged during the night from Thursday to Friday. This charge covers all the purchases you made from last Thursday up until this Thursday.
For example, let's say you made purchases on Monday, Tuesday, and Friday. You’ll see a charge for your Monday and Tuesday purchases on Thursday night, while the Friday purchase will be included in the billing for the following week.
How to change your billing method
If you wish to change your billing method from a weekly basis to a transactional basis, please reach out directly to our support team by email at support@felfel.ch or by phone at +41 43 536 74 51 (German & English) or +41 21 515 40 17 (French & English).
Possible explanation 2: My physical FELFEL badge was lost or given to someone else
If you have a physical badge linked to your FELFEL profile, and you can’t find it anymore, or you recently left the company where you used to have a FELFEL fridge, it’s possible that someone else might have used it without realizing it belongs to you. If you remember having a physical FELFEL badge (see the picture of the badge) and notice any unexpected charges on your account, please reach out to our support team. You can contact them via email at support@felfel.ch or by phone at +41 43 536 74 51 (German & English) or +41 21 515 40 17 (French & English). We’re here to help you unassign the physical badge from your account and adjust your account balance!
Possible explanation 3: My payment method was unsuccessful
Sometimes, the payment method you have linked to your FELFEL account might need a little attention—it could be outdated, blocked, or there may not be enough funds available at the moment. Our system automatically tries to charge any negative balance based on your billing method. This means that if your payment method gets fixed later on, the charge might have not happen right at the time of your purchase.
To check if your payment was successful, just have a look at your transaction history. If you see a check icon 
next to the amount of your previous purchase, that means it went through!
