Paying monthly for service I can't use fully = ****

I've had an E30 error for the last two days. I've attempted the self service tools to clear it - with no success. I contacted your contact center and spent 40 mins on the call for your consultant to tell me that I need to go to a MultiChoice office. Furthermore, I've spent money to get installers (multiple times this year) to resolve the signal strength when there is none. As some channels work and some don't work at all due to "poor signal strength". At this point, I'm convinced this is a ploy (****, really) to get us to buy new decoders.
