Service and Standards just not what is expected

1st car - New Porsche cayenne - purchased P/Randburg. 2nd - New Porsche Panamera 4 - Purchased Porsche JHB. 2 year mark, vehicle blows fuel pump, car was towed immediately, parts ordered, descent loan car provided, customer kept comfortable, vehicle repaired (10 days). 3rd - New Cayenne Diesel, 2 year Mark, major oil leak, advised on service 1) can't service due to oil leak 2) No call back with repair date 3)called myself, told maybe in a month, no call back, sent email to management. 3) Went in 15 April - Pretoria. 4) loan car provided, badly kept Porsche to the point where I am advised to just push the electronic lift tailgate down to close it? After years of being with Porsche, I am disappointed. Porsche was the best, they used to care about the feeling a customer got at every stage of owning a Porsche. Having two brand new cars under 2 years old needing major repairs? Giving the customer a loan car that is questionable? My car is only 2 years old and it should not be in for repairs and I should not be inconvenienced in this way. The small things that used to set Porsche apart from the rest of car dealers in SA and which were part of the owner experience are well and gone.
