UN-APPROACHABLE ABSA EMPLOYEES

After being unemployed, and not able to make my vehicle finance payments as regularly as I did over the past 2 + years - I find myself dealing with an incredibly difficult, intolerable individual at Absa Risk. So lets put this into perspective: I am 4 months in arrears IN TOTAL . I have taken every call from ABSA, rep**** to every message, kept them 100% up-to-date on my situation - I have made payments when I have had the cash. On the 1st October 2018, I informed Jason (the risk guy at ABSA) that I started a new job, had paid R4600 into the account and would pay A MINIMUM of DOUBLE payments from the end of October until the outstanding was paid up (4 months). He sms'ed me to tell me "that this would not be acceptable and that they required 60% of the outstanding before they would enter into any agreements with me". I then messaged him today (2nd Oct) to say that I would pay R20 000 (I only owe R22715) at the end of October when I got paid, but I really needed a car to get to work . Today (2 October) he tells me that this is also "not acceptable and I must make payment by the end of this week". Really ABSA ???? How can this be customer centric or cost effective to yourselves to have this attitude, or conducive to any working relationship? I will provide all communication entered between myself and Jason to validate these statements. Please can a humane individual make contact with me to resolve this issue in a professional manner?
