I app**** for a pricelock contract months ago and never got a response. I was one of their first customers and always paid for the top subscription. To my amazement I received a call from a representative to offer me a miniscule discount. I have 3 decoders which were all working. After accepting the discount the rep said he had to cut me off for a few minutes to reprogram my subscription. When my service was restored one of my decoders wasn't working. I immediately informed them of this. After a few days of spending hours on the phone and running between decoders and smartcard etc. I still didn't have my 3rd decoder working. They insisted it shows by them as working. However on my end it's not. I have given up on their pathetic service and cancelled that decoder. I'm sick of their bad service.
