no feedback on application in 3 weeks

Good day<br> <br> Its been 3 weeks to date and still no one can tell me what the delay is and i was told finance was approved and that they were just waiting to hear if i should give a deposit or not.the dealership cant even get an answer out of standard bank even the person at the bank who was dealing with my application doesnt even call me back and is completely clueless.<br> <br> How can you treat clients like this its unacceptable
