Complaint Review: MMC Sight Inc

About a month ago (10/12/2009) I sent in the slide  of my Taurus PT-145 for a tritium night sight upgrade at www.ptnightsights.com
They stated a 2 week turn around; recently I have not been  able to reach them by phone. All I get is the "you are next in line" then after a few minutes , you get disconnected. I've sent several emails, but no reply.  So today, I called my credit card company on them and also reported them to the better business bureau which have them on record with an "F" rating, so that's not good.

I googled around and found this forum about how bad they are:

Now, I'm afraid to loose my slide which is registered in my name and have it fall in the wrong hands.
