Car Licence Renewal

I went to Valhalla Post Office today, to new our car licence disk. First off all, Card Machines is not working, Secondly, the lady at the till said, if the vehicle is on his name I require an affidavit. According to information received, the below documents is needed:

If someone else renews your licence on your behalf, you need to make sure that they have:

A letter giving them permission to renew the licence. A certified copy of your ID and their own ID. The appropriate fees. Any penalties and arrear licence fees if applicable.

Cleary they do not want to assist customers. Worst service!
