Waste of time

I've had numerous issues with my car purchase.i booked my car in about a month back 2 have the ac replaced and my speakers that are faulty.these r issues that have been taken up with them verbally and via email. They told me they fixed the ac but it still makes a tractor noise and now a fumes smell is in the car when the ac is on also my car consumes way more petrol since the so called service and fix up.my speakers I was told is out of warranty and they can't replace it.the warning light in the car STILL goes off 4 some lights. I have a maintenance plan with u guys. I've been told 2 bring the car in at my convenience 2 have the light situation sorted things is I will need a courtesy car which I will prob have 2 wait a month 4 as they neva finish on time. My last car check in was with them 4 nearly 2 months and still nothing has been resolved-it's just pathetic and crazy to put up with such poor service and run around around to avoid any cost at there expense
