Substandard Equipment substandard service

Fault Reference ***0. Logged last week. Still no response and no change. Internet still dropping out. Was promised a technician within 3 to 4 hours after this was escalated. It has been 72 hours since then meaning this fault has been logged 6 days ago without resolution and without feedback. If this was a white area this would have been done. You install substandard equipment and substandard cable. I have seen the cable used in white areas and the **** you installed in the coloured areas. And we pay the same amount of money. Substandard equipment and substandard service. Why dont you just get the hell out of our areas and service the white people you give the top class stuff to? Why even bother to offer a service here
