Boo Boo Mistake

ABSA approved my finance to buy a new vehicle. When I have to sign at the dealer 22 Sept. They didnt send the contract for the dealer. Tshepo Ngune from ABSA said that somebody make a Boo Boo mistake and press the wrong button at ABSA. How can you send a letter of approval to the dealer and when the client must sign you said somebody press the wrong button. I am a client at ABSA for 33 years and this was the biggest dissapointment of my life. Tshepo said they will handle this problem and will give me a better interest rate . Common Tshepo what is .25% after you put me in a bad sittuation.
