Horrible customer service from Standard Bank Vehicle Asset Finance

My car was financed by Standard Bank Vehicle Asset Finance I had balloon-payment so after finishing paying off my monthly installment I phoned call asking them about my balance for balloon-payment they told me "I do not owe anything" they asked me for my address so that they call deliver my documents so that I am the owner of the vehicle a month later I got a call from attorney telling me I am owing balloon-payment I wont pay that as I was told I am done paying I phoned them asking for recording of the call I made late last year they told me for two days since then I have been waiting. Standard Bank Vehicle Asset Finance can I have my documents for my vehicle I fully paid? as for Balloon-payment sort it out with your *********** staff Yamkela Ngqengqa and his Manager. Next step Ombudsman I demand my documents for my vehicle I fully paid by next week.. ID number *** Cellphone : ***
