Cooking Oil review: delaying the shipment

Hello everybody,
we are the tereksy for the general commerce TGC in Mauritania . we have been importing cooking oil from this Company "empire trading(m) sdn bhd (886748-T)" this time as usual I send my order on 02/06/010 for 12 containers of Cooking Oil, But the deposite was received after 20 days of that, due to swift mistake . the company send us that they are no longer accepting the prices of the first prophorma invoice .the director of this Company obliged us to accept and signe a new prophorma, with a very high prices .we have accepted to signe the new prophorma, in order to avoid problems with him .this company spent approximatly two weeks, without precising to us the day of the shipment .We send to them that if they don't precise the shipment day, we will confront the justice with him . He reacted that the day of the shipment will not be befor the 28/08/010 .we don't accept that, furthermore, we are no longer trusting him .
Please tell us, how can you help us in this problem
