We are the group of investors invest the office which name Chinese Business Hub in Dubai South and also the project of Avani Al Marjan Island Ras Al Khaimah Resort . The company offers us the guarantee annual return but we just received one return and even not received any return from the company from one and a half year ago. The company just gave us difference reasons to delay the payment during this period. And they mentioned both projects are under Shariah Compliant. For such situation, can we report the police to claim them with criminal or we need to arrange the Civil litigation? We many need to get the legal advice from UAE. What we can do?
