Proof was given, but due to lack of service

My loan was approved by African Bank on the 11th of October. I received an sms to state that it is approved. On Wednesday I Contacted african bank and they said they needed confirmation from my workplace which they got, the money will be paid in within 38 hours. Friday I Co tacted african bank again, excuse this time they waiting for authorisation from my bank. I received a call from the supervisor to say the process took to long everything is approved he just needs to resubmit my documentation and my money will be paid in by the evening. Now I phone and get told I was rejected without any reason.
