I had a little problem at Cody's at Sumter Landing once, and did not get to speak to a manager. I went online to their web site and sent their corporate headquarters my comments. Lo and behold, with 48 hours I received a call from the local Cody's manager and they addressed my issue to my satisfaction. Maybe you should do the same.
