I had a trouble with the three. Always paid on time. The counters stood with me, the water paid for them (indications on the site entered). We repaired all the pipes for water in our house, at the same time decided to change the meters (the deadline approached the replacement). I learned from them that I am just changing, then calling for a clamp. In reality, it took about 2 months (they did not go to the seal, motivated by the fact that not everyone is ready in the house (remember, the seal broke everything)). So they said that for this period I will pay on average indicators. I got the bill for the apartment, and there was four times more hot water. I wrote it and forgot. A week ago, a polite lady called, asked why I didn’t pay. I said a lot, I will not pay. So after 30 minutes on their website got another payment card with the norm numbers. Which I paid for.
