5 months Blocked sewer

Good day my name is Murendeni Magonono. I reside at 2791 Union Street Protea South. I have been reporting a blocked sewer for the past 5 month with our local deposit (Avalon) with no help. All I get is reference numbers but they didn't come to fix the problem. Please assist. These are reference numbers I got with no assistance. ***, ***,***. Please assist. The situation is now unbearable. Cnllr Noxolo Nofemele once promised to give me feedback but I didn't get any response afterwards.

Your assistance will be highly appreciated.
