Does any one know about al khaleej enterprises as they are operating from (mezzanin # m-1, plot # 18-c, main zamzama commercial lane 4 phase v, dha saddar town karachi south.) with ntn # 7468560-0 named shahid nawaz and cnic # 3530123193647. They are asking down payment of 20% as a security to be sure that we will not back up after verification process. Any advice would be much much appreciated.
