Kia Gleneagles not giving credot back

I ordered a remote for my car. And i paid for it. A week later their admin lady called and said i am due for a credit return because the remote is under warranty. I waited for a month for feedback but no feedback was given. I called them and they said they will follow up and no feedback was given. I went to their office and the Eugene the manager said he will give the request to their finance lady the next day. I waited for a week for feedback. No feedback. I called again. And Eugene said their finance lady is not there. Then i escalated to twitter and got a response back within 5 minutes saying they will send the request through and an agent will be in contact. A one Randy Robertson. He said that glhead office approved the claim and they will sort this out with Kia Gleneagles. I have been waiting ever since this has been more than two week since i heard from Randy or any kia representative. This cannot be the type of service a luxury car dealer provide.
