Change of Ownership from Wesbank To My Dad

My dad has finished paying off his vehicle a few years back and the change of ownership is not yet done. I reached to Wesbank and emailed back all the relevant materials for the case to be finalized. I was Advised by Mohale that the process should take about 10 days. I emailed Mohale twice to follow up on the case and he did not even bother to respond. I need the documents to be sent ASAP.
