From reading this thread, it appears that both the vendor and buyer made some errors. As someone who tries to see both sides before making a judgement, I find it difficult to lay 100% blame at PSA's feet. Sorry to hear that your experience was not good, OP. I sincerely hope that you find a company without fault, and look forward to your glowing review, once found.
For the record, I neither know the OP, nor have any first hand experience with PSA. That said, this review would not dissuade me from buying from them.
Best to all,
