Sorry to hear about the trouble! To get started, Square does not currently support pre-paid bank cards or online-only accounts, as they do not support withdrawal in case of refunds or chargebacks. If you are trying to add one of those, you would receive a routing number error or a failed bank verification.
If this isn't the case, please reach out directly. Someone from our Support Team would be happy to dig into this more for you!
