Overcharged by Deal Now Seongnam for service

I purchased a device from Deal Now Seongnam on September 7, 2007. Shortly after using it, I experienced arrived significantly late. I contacted their customer service on multiple occasions, but they have not resolved the issue. I spoke with Helen U. who promised to escalate my case, but I've heard nothing since.
