Poor service

My son has a VW POLO GT which was front damaged. The repairs to the damage of the vehicle is good... Well done there. However, we've been waiting for almost a year for the correct grill...a Polo GT has a specific grill! Whenever we make enquiries, we are always told "it's on order and will arrive soon"... Really now, this is very disappointing and unprofessional. The insurance will know about this...
