Lack of service costing me money.

I upgraded my home system to a Explora package with extra view on the secondary decoder(a Service which I have had since the launch) My signal on the explora decoder is fine but I have an E16 error on the extraview channel. I have made 4 calls of 20min + to the call Center and without resolution.<br> <br> Please can someone from the service center contact me that is competent enough to resolve this apparent \easy error"for me"""
