Wesbank unacceptable service

Worst customer service ever! After 3 months they have still not couriered (as they told me I cannot fetch it myself) my Natis document to the new owner of my car. I have sent numerous emails, proof of payments, proof of addresses and contact numbers to where this piece of paper should be couriered. They also do not bother to let you know that it was never delivered. I have lost all trust in the Firstrand group. Something that should have been so simple has now turned into a huge frustration.
