Unhappy customer

Just poor. My subscription has increased dramatically (without being offered an option) but my connection remains consistently unstable. I have reported it numerous times and have paid for an extender which didn't solve the problem and now they want to charge me R500 to come out and fix a problem that should be part of the service they provide. If RSAWeb cannot provide the service I am paying them for why on earth should I pay more for it? What an absolute joke. I live in a small flat and I cannot get a consistent connection throughout even with the (very expensive) extender. How is their slow / intermittent connection my fault? Poor poor customer service.
