Mountain Top Reptiles

Anyone ever delt with mountain top reptiles? I just got a Tapinauchenius gigas from them and it died a day later for an unknown cause. I fed it when i got it home and it ate fine and then i got home from work the following day and it was dead!! It was in the same room as my other 9 Ts including a Psalmopoeus pulcher which is the same kind of care and it is fine. I have tryed to e-mail him 2 times and no answer back yet. If anyone has delt with these guys let me know cause i dont want to misjudge him if he is a good dealer.
