KEY DELTA DEALERSHIP A SCAM

My sister has been without a car or 3 months to date, she was promised the car will be ready on the 17 December which moved to Monday. Sad thing is that the motor plan is still active, she's been paying installments and insurance for 3 full months without her car nor a courtesy car from the Pietermaritzburg dealership where the car is being repaired. She's been on leave since 17th December supposed to have gone home but she couldn't. This has affected her on badly, the inconvenience caused by this company towards her personal and professional life is unbearable. Why are we receiving such bad customer service from key Delta? How do they justify keeping a customer for 3 months without a courtesy car? I beg STAY AWAY from key Delta dealership as they demonstrated that customer care doesn't exist it's least of their priorities. Why are they selling us motor plan if the car breakdown a client will be left stranded? What are year customer values, vision and mission objectives? Worst of all they don't call if we don't call them
