This is a very common practice here in Doha by real estate agents. The issue has come up several times earlier also at QL. However, it is indeed surprising that a company like Al Asmakh could also be involved in such an unethical practice. You may try approaching Rental Disputes Committee and see if they can help you out. The last resort is to take the company to the court of law. But this is a time-consuming process and it may take you several months to get a verdict from the court. You may be required to be present at the court on all the dates set for the hearing. The real estate agents know of all this. Hence, their unscrupulous acts.
