Has anyone experienced sketchy billing with KCP&L before?

[Hammock Parties]

I moved into a new house last month and didn't use hardly any electricity for the first three weeks during the moving process. The last week of the month I was moved in and using electricity normally.

By KC P&L's own daily usage tool, I used about 200 kWh that month. They sent me an "estimated bill" for over 800 kWh, though, as if my A/C and appliances had been running all ****ing month long.

I bitched at them over e-mail for two weeks and finally got the bill corrected to reflect the 200 kWh charges.

A day after the April bill was corrected, I suddenly notice my daily usage charge for the last 16 days has magically gone up every day. I had an extremely high use on 5/8 due to the shitty AC I'm trying to get fixed (112 kWh), and the charge for it a few days ago was about $15. Now suddenly this morning it is over $20.

By their own residential rate page, cost per kWh is $0.13328. That $14.92 for a 112 kWh day.

Monday I used 22 kWh, which should be $2.93, yet suddenly it's $3.94.

I know for a fact they tried to rob me blind last month, and now this seems sketchy as ****. Anyone else got a similar experience?
