Still no Natis dcoument sent

I settled the balance owing on my vehicle on the 12/12/2015. Wesbank after numerous calls have still not sent my Natis document yet. Its still in Gauteng and I'm based in KZN. Everytime I call I get a new reference number and told the previous request was rejected??<br> <br> Wheres the courtesy call or email to advise if there is an issue etc? Why do I need to keep calling in to check?<br> My other vehicle which was with MFC was sent to me within 2 days of me settling the final payment.<br> <br> I'm tired of tracking numbers - WES1512/07/011, WEF1512/04/943 etc. Why such a long delay to send something so simple, I still have to wait for delivery time - disgusting service for such a large company.
