Error Code E4 still flashing after 40+ hours (ComCrypt 4000 Decoder)

<p>Since 16h30 on the 10th of Oct 2016 our decoder displays this E4 message whenever channel 1 of 7 (MNET) is selected. Channel 5 (Sport) however functions 100% correctly. We have logged 5 different calls to the call centre ********** and every time a different story. On the 10th we were advised that it was a general MNET terrestrial feed problem, and that technicians were working on the problem. On the 11th (2 different calls to call centre) we were told that MNET terrestrial did NOT have a feed problem, and that our decoder must be faulty (but channel 5 is functioning perfectly)! Last night ****h Oct) we called the call centre again, and this time we were advised that it was a general MNET terrestrial problem, and that it had been escalated to the technical department. NO time frame could be provided to restore the service. It would appear that the call centre operators does not know what is going on, as they contradict each other! What is the truth????</p> <p> </p>
