Requesting a full ID copy of the bank's representative to complete vehicle re-registration

I obtained vehicle finance from Standard Bank in 2019. After paying off the car recently, without any defaults, I received the paper work from the bank to do the re-registration into my name. Nevertheless, the sent ID copy of the representative was a half-copy, with the post-office in the Eastern Cape only accepting full ID copies. I contacted the bank at least 3 times to get the full ID copy of their representative with no luck. What does one have to do just to get a ID copy to follow due process?
