Poor service and customer care

I only gave 1 star because there is nothing lower!! Been receiving an E48-32 error on primary decoder for days now and yet the secondary decoder is working fine for now....it usually also goes without service for weeks on end saying it cant pick up heartbeat of primary decoder. There is nothing wrong with both decoders as they havebeen tested. Can never get through to their call centre and we are tired of calling out an installer who will seemingly fix the problemfor a few days only for it to return again
