No reaction from City of Cape Town

My water supply is since last week Sunday (20th May) between low water pressure to no water at all. Tuesday last week I contacted the COCT to report low water pressure. Nobody came out. Since Friday evening (25th May) NO WATER at all. I report it again on Saturday. They promise that turnaround time is 48 hours. I'm phoning, sending emails, NO REPLY. Almost 150 hours since 1st report, 53 hours since 2nd report. THREE DAYS NOW WITHOUT WATER. What more can I do? Stop paying may bill?
