Atrocious service by DG, Digital Generation, Asus South African partner

My otherwise perfectly working unit was delivered with a faulty power adaptor (simply dead out of the box) and I've been forced to run it with a 3rd party USB-C adaptor since. I've now engaged with the ASUS/DG team since March 15th, trying to get the faulty unit replaced. Like a robot they insist that I send in my working laptop in for assessment which is ABSOLUTELY RETARDED as it is 100% clear that it is the broken adaptor, not the laptop and I can not let go of my work laptop for an unforeseeable time.
