Vehicle finance captured under incorrect person

I recently purchased a car and had my finance approved through Standard Bank. Three weeks ago a family member contacted me saying that my statement from Standard Bank was delivered to him with all of his details captured instead of mine. It has been 3 weeks and countless hours on the phone since trying to get this sorted out and I have had absolutely no feedback that something constructive has been done. I keep getting the runaround from one department to the next and not one of them can explain why this has happened and what is being done to rectify this error. If I don't initiate the contact nobody bothers to get back to me even though they promise to after speaking to me. I am sorely disappointed in this shoddy service as i expected better from the bank that I have been with for a decade now.
