How tf do you have tenants paying A FULL FIRST MONTH'S RENT and then they can't move in until half of the month is over... and then you expect a full months rent again on the first. AND they only serve certain customers requests!!! They can satisfy early move in for certain individuals while others are just left in the dark and lied to about their apartments. I haven't even MOVED into my apartment yet and I regret signing a lease with this untruthful and uncaring company.
