It is important to report an ATM cash error immediately. If the ATM provided a receipt, keep it as it contains important location information. If you did not receive a receipt, make sure to record the exact date, time, ATM location, and, if more than one ATM at that location, the ID number of the ATM. Then call MyBambu Customer Service at (833)883-2628, and we will work with the ATM owner to investigate the error.
