Damage to property

One of the driver's was traveling on the N1 passed our house and the tires of the truch came loose and came straight through our wall and damaged the walls on my kitchen door and frame now we sitting with the bill to fix it we got the truch information and registration number and disc but the company doesn't answer the phone... And the driver is from Swaziland and the truch is a Go registration.. So what do I do in this matter
