Total non-delivery of service

We are a business in the Gansbaai Area, Gansbaai Electrical CC. On 18/08/2015 we had noise on our landline, and our DSL was dropping. Upon reporting the fault I was sent ***. I received an SMS stating that the problem had been resolved and all was well for a few days. On 25/08/2015 our problems returned and we reported it again, receiving ***, 4 hours later the report was \resolved""; so question how he established that. I assured them; we had tested every possibility; even unplugging everything and connecting a external phone. We need our internet for our business! After several more calls and long waits the report was escalated with ***. Still no technician;still no DSL!! We're reduced to using a tablet for internet!"""
