The Status "Direct Debit Processing" means the Payments have been submitted to EziDebit for processing and we are waiting for a response back from EziDebit (and in turn the account holders bank).
For Direct Debits, this takes several days to process. Each of the transactions go through different banks and they can get a response at different times. Generally 3 - 5 days after charging. It will change to Payment Complete (and through other status's) if successful or Error if not.
You'll probably get an email from EziDebit when the transactions have processed as well.
The updates happen at 1 am in the morning. Please wait for 3-5 days to let the transactions to complete.
