Terrible client service over and over !!!!- - still awaiting feedback from Ranjiv at KIA and Ashwin over 6 days later

I am still awaiting feedback on what will be done about my dissatisfaction from Ashwin and the manager Banjiv. I called again Friday and asked Ashwin to please get his manager to call me back as promised over 5 days ago!! This is terrible service. Please can this be escalated in management to someone who actually cares about their clients - how does a manager of your brand who represents KIA not even bother to uphold his commitment you call their client back. I will go into the KIA in person if needs be until this matter is resolved. I would not recommend this branch of KIA to anyone !!!! the customer service email I sent over 6 days ago still hasn't even deigned a response!
