Poor rate o response at call center

I am not happy with the rate of response at Absa's vehicle finance department. I called this morning and I had to wait 15 min for someone to respond and that person could not even answer my question, the then put me on hold for another 10 minutes. This is unacceptable!!! I called again this afternoon and I waited another 20 minutes before someone answered but did not say a word, a could hear background noises and a computer switching off, I am really not happy with the level of service.
