Loan approved, Debit loaded but no loan paid out

I applied for a loan, it was approved, I signed documents and agreed to debit order. I received sms confirming debit order is loaded but for three days now have not received the loan money. I have emailed two days in a row but received no response. Has this company gone bang. WARNING- do not apply! I will update should they debit my account for a sum they did not release to my account.
