Living in a flooding yard due to sewage leakage.

I have been struggling with sewage problem from the 10 April 2026 till to date. I reported the matter to my local ward councillor on the 13th of the same month there was still no help. I spoke with him on WhatsApp on the 19th of the same month, he answered me on the 20th and said he will follow up on the matter but still no help. My uncle phoned him on the 4th of May, and he said he will follow up again but till to date I still did not get any help. I have lost hope on our Municipality. It has been a month and 3 weeks we are living in a disgusting situation, and it seems like nothing is going to get better any time soon. We really need help on the matter.
