Forced to accept an incorrect engine

I bought an Audi A5 CNC engine (Quartro) for my vehicle only to be deliberately given an incorrect engine which is a CHH (not compatible at all). I notified Majestic Spares the following day (14/01/2026). VW/ Audi advised that the incorrect engine given to me can not be used on my vehicle. Today (19/01/2026) I was sent an old rusted engine. I rejected the engine because it's old and I have paid for a new CNC engine.
