Liliia Keep in mind that a reply from bunq support can take up to a few days, keep your support ticket open and you'll be notified once you have a reply !
Unfortunately, depositing cash isn't really possible in practice with bunq. That's why I also kept my "old" bank account at a traditional bank (Rabobank), among others for those few times a year that I want to deposit cash.
We're reading a lot of posts like yours here on Together, we hope bunq might find a different solution to deposit cash (in the Netherlands)!
