Conservice Utility Management & Billing review: Billing for sewer charges

I am being charged 150-170 per month for sewer charges which makes the whole billing amount to 250-270/month. Why am I being charged so much when the same usage used to cost me 95/month 2 months back (whole bill amount). When asked where to see the units spent for the previous months vs now in the meters that I can see, there is no clarity as to where I can check that. As a solo resident, it doesn’t make sense that I have to pay 250-270 per month to conservice for this.
