This company operates under 3 names, Premium PC Solutions, Global Tech Services and Sam Technologies. They not only did not fix my computer but calls to their business are routinely disconnected when I try to reach them. I have been promised a refund but in over a month have not received one. I received an email from a manager promising a refund in 3 to 5 days but, of course, did not receive one. Cannot reply to email as somehow it will not go through
