Bad service

I have sent a WhatsApp request with my license disk so I can receive the correct parts even before parts where dispatched, I was blue ticked and no one responded. I sent another WhatsApp message in the morning before they closed and still no one responded who has to pay for the parts to be returned and get the correct once’s?

CAN I GET THE CORRECT PARTS SHIPPED AND THE ONCE I HAVE TO BE COLLECTED!!! ASAP as I need to travel for work by Tuesday latest this must be resolved!!!
