ABSA bank lack of service

It has now 2 months since we requested the paperwork to a vehicle which we have paid in full. When we do get a response it is to ask us to submit documentation which we have already submitted 3 times, but mostly our emails go unresponded to. Added to this, I am getting non-deliverable responses from the ''actionline'' email address for complaints. I am currently out of the country so it is difficult to make contact telephonically, when you are on hold for 20 minutes at a time. Shocking service.
