Property Price Stockist

I have been living in Ezdan Oasis since 2019, the property management company raised the rent from QAR4,600 to QAR7,050 during my annual renewal taking advantage of FIFA cup and maligning the reputation. Now I have signed up a contract for 7,050 however new contracts are signed at 4,250. I need to check if there's any government or minstry dealing with these issues where i can register my complaint for these stockist and black bees.
