Sometimes, your bank can block fees withdrawals or deposits from your Mosaic account to your linked bank account. To ensure all funds transfer smoothly between your Mosaic and linked bank account, please call your bank and request the following IDs to have any blocks removed:
1310281170
1043575881
Once complete, please let the Mosaic team know as soon as possible so our partners can retrigger any deposits or fee collections that may be outstanding due to the previous block.
