Order of Tribunal ==> court order, telling you to pay up the
amount you owe.
Writ of Seizure ==> you don't
pay them, they will come over to seize your PC.
And don't even think about sabotaging your PC, unless you want
to get into further trouble.
You owe them $3,056.00.
Presumably that includes interest plus late payment penalties,
anyway it is more than what the PC is worth.
Check if they can seize other things, like your motorbike, your
tv etc.
