He HAS left a house already, he paid everything till the last day. But now a Landlord asks him QR 15,000 for the next 2 months, as IF there is a Rent agreement between them.. right, djdesi?
well, as canary said, you have to hire a lawyer, or at least to consult with one of them...
BTW, QR 15,000 is the price for a whole villa?? WHERE??
