I got ripped on chip install-Help!

[ucrtwf]

Hi guys,
I was wondering if any of you have had "themodchip.com" install your chip?? A couple of weeks ago I sent my PS2, along with my reciept for $117 (for the dms4 pro and install) to the address they instructed. They said it would be 5 days before I would get it back. I emailed 2 weeks later asking for a status and they said they couldn't do the job and they can't give me my money back, so I would have to dispute the charges on the credit card. The biggie was that they didn't say anything about my console being sent back. I replied back for more details and I got nothing (yet).
Anyone have any ideas? This suks.
Thanks in advance,
Tim
