I used this company once before to recover a client hard drive in 2007 and they where great. Its now 2009 and I sent another hard drive in and they wont return emails, wont return phone calls. After spending a great deal of time asking for help, when they finely do respond they don't even answer the questions asked and blow you off. I am very upset that my HD is still their possession and i cant pay it off right now since they wont give me a balance or receipt of what I've already paid to reconcile with my records before sending the next check.
