Poor service (wesbank motor finance)

Please note that the settlement amount for my vehicle as financed by Wesbank motor finance was finalized on the 25th of Feb 2015 and furnished to the institution I was then advised by agents (wisal) and (Ngesi) that my NATIS documentation would be couriered to me by no later than the 4th of march well passed their turn around time of 5 working days I'm still waiting for these documents to be sent to me despite several Phonecalls and e-mails <br> <br> I find this to be unacceptable and need this to be resolved as soon as possible
