Its been a month I have been resending my email still no response from ABSA

I have sent ABSA emails after emails since Beginning of may to enquire about the balance on my vehicle as it does not add up, I think they have blocked my email as I tried sending from a different email and I got auto response that someone will get back to me. I am still waiting for a response. My whole financial life is with ABSA and it sad to see how badly they treat most of their customers, can a bank really employ people that disregard customers that make it possible for them to have a job? I have even emailed their complaints department no response, I have emailed every email address on their website and still no one has gotten back to me. Why does it have to get to the point of us going public before someone pays attention. I am really reconsidering moving my vehicle and home loan to another bank as really this is beyond the level of disappointment.
