Extremely bad service deliverance

My partner and I have been greatly inconvenienced in a way that we've decided to shop elsewhere for a new vehicle. The car was delivered end of April 2017, one cannot start imagine how tedious it's become, after subsequent follow up with the dealer, from a sales consultant to service advisor who was meant to expedite matter to relevant parties. The service is extremely poor in delivering, we've identified errors and had alerted Mandie Galvan, from the likes of a licence disc to damaged parts, where driving was not pleasant from a rattling sound in the boot. I'm exhausted, I need a refund.
