NO WEDDING DRESS DUE TO DELAY BY COURIER

I ordered a dress online. The initial ETA was supposed to be 4 February for my dress to arrive. It arrive at Johannesburg on 4 Feb 2016. The tracking report says held awaiting customs clearance the whole day of the 4th. Then it went to Shipment Awaiting Physical Release from Customs Control Area. The status remained until 8 February. Today its still says that. I have emailed TNT, phoned their Helpline with no help.<br> I am getting married on Saturday 1 Feb with no dress. I have an appointment with my seamstress tomorrow which is the only one I could get. How do I get my dress out of customs - why won't someone let me know if they need anything to release it????? Im Stressing with no dress to wear to my wedding!!!!
