Bad treatment and unhelpful

I lost my dad in December 2020.He has 2 payed up bakkies that were financed by Standard bank. I could not find the log book of the bakkies. I went to standard bank (mall@reds branch, Centurion) as the bank that financed them to give me the copy. They sent me from post to Spiller for good 2 years (2021 and 2022). I dnt know what to do anymore as they cannot be changed to my name and on the other side I cannot renew the disc and I will be penalised for not paying for it for 2 years. I'm really disappointed for the bad treatment I got from standard Bank. I dnt trust them anymore. We are thinking of changing the bank as we are all bank with them in my family
