Pathetic Customer service!

I called Absa Vehicle Finance head office to get assistance regarding the change of ownership on my vehicle that has been settled. After being transferred twice i explained for the third time that I have a letter from Absa on which the stated proxy is not recognized by the post office nor traffic department. I have been trying to do the change of ownership since mid May and everytime i go back to visit one of the branches they are adamant that the guy listed is the proxy only to go back and forth between the post office and traffic department and branch and still nobody can assist me. After asking the lady to please assist me SHE INFORMED ME TO PLEASE CALL BACK LATER BECAUSE SHE IS GOING TO LUNCH NOW. How is it that when you have a client on the line u tell them phone me later I am going to lunch? I still have no response with my query and this is actually pathetic customer service!
