No proper help with decoder problem

I am shocked and very disappointed with the on line help I received, not only did it cost me time but and expensive trip to have my decoder checked. I was chatting for hours on Saturday trying to get my decoder to work as there was a no signal error message. I was told to try various options, after sending screen shots and asking questions, not once was my questions answered, just kept been told to take my decoder in to have it checked. Never once was I told when I reboot must I choose the manual option and then universal even when I told them that the date was showing incorrectly, which according to the office where my decoder was checked said that was the key they should have I understood and told me which options to press, No instead they just want to get rid of me and me and force me to make a trip to have the decoder checked …nothing wrong with the decoder just poor on line help. Gosh if they have people working in a support role, they should know how to help with resetting everything to do with errors and when a customer asks questions to be able to answer them and not just sent irrelevant links. I’m mad and sad with the inconvenience I had to endure through untrained support staff.
