ista-na Ista bills, iista-na, or ista north america scaming me and other residents jacksonville, Florida

I moved in to a two bedroom, one bath apartment. And the bills started at $50. They are now $70-$80+. Its just me and my wife.

We used to live in the same complex with roomates. It was a 2 bedroom, 2 bath apartment. And 4 people living there. and the bill was only $30-$40.

When I go to the property manger says she fixed it the first time and lowered it $20. The next month she did the same thing. But this month she said call the company. The company number just keeps ringing or just hangs up on you.

Other people in my building are having the same problem. And others that live in other complexs but use the same company. Have the same problem.
