We cant help, wrong department and the cycle continues

I recently contacted ASBA to help reschedule my vehicle payment terms, I explained to the lady that I would like to start paying more and reduce the number of months that I had left to pay, so that I could pay this off faster. I received no correspondence and later decided to log a complain as I thought I might then receive some help. ABSA then did get someone to contact me, but the person who did contact me could not assist as she says she is from the incorrect department. I then received an email, from must be the manager of that department, saying they could not assist, as they are the incorrect department, I responded and asked if they could please point me the right direction, as ABSA put me in touch with this department. it is now 32 days later and I have not heard from ABSA at all. I just need a person from the correct department to please email me, as I am unable to answer calls during the day, so that I can send them the information of how I would like to get my vehicle instalment adjusted so that I can pay this account off sooner, but I am just not getting any joy, no one at ABSA vehicle finance can assist me. There is just no help?
