Unresolved Vodacom Issues Continue for Months

My last complaint (21 Sep) was about neither myself nor my direct neighbours getting Vodacom phone of data signal within our properties since some cell masts were removed. The issue has been 'escalated' more times than I can recall. This situation remains the same. When I tried to cancel both these contracts I was warned of penalties. I have still been charged full costs for both services which only work when I stand outside the property. This is not only the worst possible service, but is plain theft if we are forced to continue paying for services we can not receive.
