I got a bill from the company www.infiniteenergy.com. I checked it and was a little bit confused. I noticed that the total sum was too large, so I started to check everything. It turned out that they added some additional fees, but it was unclear for what I needed to pay. I called to the customer services, but the lady told me that she couldn’t provide such info. I needed to come to their office. I think that they have tried to overcharge me, and they have succeeded.
