Bad Service Loan declined no valid reasons

I app**** online for a Old mutual loan. Was pre-approved and an agent contacted me back as well to do the full application. I provided all the necessary documents and accurate information to the best of my knowledge. I was then approved for 4 loans for various amounts and chose the one option of R13000 over 24 months. Was told by the agent i will be notified when the money has been paid out. Later in the day i got a call stating that i was declined based on affordability which is insane and given no exact reasons as how they based this on. I then called back to have to have application reviewed and was assisted by a Nadine Gouws who re-did my application and was approved for same amount again. She said she would send this onto admin department. I have a very good credit record with no negative information and have no issues with affordability either, accurate information was provided and documents were submitted. I am disgusted at the service received thus far by old mutual if this is the case then i would rather apply elsewhere. Can i please get this resolved and my loan paid out.
