I moved into one of their brand new properties called The One and there were issues from the start. The building and its amenities were not fully ready until a month or two after move in and they close the pool for maintenance constantly for weeks at a time.
The problem I am still dealing with after 5 months of living at this place is still not fixed. They have been using ESTIMATED READINGS for my building and they are completely wrong because my electricity bill is in the high 300's for a 4 bedroom that only 3 people live in. When I called FPL (Florida Power and Lights) they told me they have been having problems with the building and getting accurate readings. When I asked the people in the building about it they just say it is your problem even though it is a building issue. They have me locked in with simple bills (utility payment app for residents) because they do not allow you to remove payment methods and they connect it to your credit score so you are stuck paying it every month whether you want to or not. Once I finally got a hold of somebody from the company they told me that they are waiting for FPL and they could only reimburse me a credit on Simple Bills which I won't be able to fully use because my bill was so overpriced. Then, when I asked to just be reimbursed from Landmark Properties if Simple Bills is not able to fully reimburse me and they denied me the reimbursement. This issue is with their building so I don't understand why I am paying for their problems with the building they don't want to fix. You would think they want to solve the issue in the whole building because other people have the same issue but they deny the fact that other people have the same problem and that I am the only one, which is not the case. I am very disappointed in how this issue is being handled and it is still not fixed after 4 months of them knowing there are extremely high utility bills for only specific rooms.
In addition, it is extremely difficult to get a hold of anyone without threatening to take legal action first which should not have to be done.
