Licence issues

We have been trying for months to change the number of passengers that can be carried on license disk. We bought single cab landcruisers and converted them to double cabs. We have completed EVERYTHING they required over weeks because they kept sending us away for more information. We have had to travel 1000km to do this as we live on a farm 60km from the town. Today they insist they need to send the original vehicle registration papers to Bhisho for this application. When asked for a written receipt for this documentation they refused and would not handle the applications any further. This is ridiculous - how can one be expected to part with the original vehicle registration documents and not get a receipt for it. They will continue to fine us for having the incorrect details on the license - and it is their ineptitude and arrogance that is holding this up.
