To flee !!!!!!

To flee !!!!!!
I lived in an apartment for 1 year rented by interimob. When we needed to reach them, we couldn't get them, despite the many reminders (emails, phone, website, etc.)
Our elevator has been out of order for over 6 months, we continue to pay the charges and had no response when we requested repair.
Also, when we returned the apartment, big surprise! More than half of the deposit was retained without warning for unjustified costs: 165 euros for cleaning costs, 230 euros for plumbing, 50 euros for repairs ... Things not indicated during the inventory of fixtures. Clearly, he takes advantage of your deposit to renovate the apartment.
Ashamed, we will not stop there. Run away if you don't want to be robbed.
