After signing the contract, when I take over the keys, it reveals that that all above mentioned product are not in order and need to be replaced or repair.
Why did you take possesion/or moved in the flat?
Now she wants to cancel the contract as well as demanding the one month rent money, otherwise she threats me to go to Police.
Police cant do jack **** if you tell them its a civil case and she has to go to court for that.
I would start the process in court(which will last a long time)meantime pay her rent through bank deposits and live as long as you want then one day she will beg you to leave...then ask her for some money to do so:)
