Just a warning to those who consider using Tekdex or Click4Support for tech work. Here's what I wrote to them. You basically deceived me. You represented yourself as a Panasonic tech which isn't true. At a very weak moment, you convinced me to spend money that wasn't necessary. You stated that the computer needed to be repaired so that we could fix the sound system. In the end, you did not fix the sound system. I did. I discovered that there were multiple inputs and a wrong one was somehow selected. Before talking to your tech today, it was already fixed. I let the tech act to fix something that was done just to see if he would come up with the right solution. He actually didn't do it - I explained to him about the outputs, and then he understood. I believe that I shouldn't have to pay as I was deceived. I shall put my review on Facebook for all to see.
