Where is the Customer service???

I have mistakenly paid Absa vehicle finance instead of Standard bank vehicle finance for my elderly father. I reported it to them on the 30th April telephonically and was given an email address to send proof of payment, ID copy and bank statement. I didnt receive any response so i called again and was given another email address so i forwarded the query again. It is now the 2nd May i finally requested for a manager but i honestly have no hope as a week has went by and no1 at absa cares that my fathers vehicle will be repossessed tomorrow because they dont take people seriously. I am very disappointed in the service i have received so far.
