2 months qeury sitll not resolved

I have been receiving statements with incorrect water billing, the readings on the statements do not correlate with the one on the metre. I logged a call on 12/12/2019(***), I even went to their offices in Braamfontein to submit evidence, but still my query has not been resolved. The incorrect water billing is still continuing. It has been 2 months since I reported this, I phoned twice to escalate my query, nothing has been done to date. Poor service delivery, I was promised turn around time of 30 days, but it is all a lie.
