To get the proposal approved

Golden sunrise

A deal was done between my company ad the venue owner agreed on a certain amount . The 1st deal was carried on successfully bt due to their conflict with the other party they hve increased their prices without further notice for every1. Now they hve quoted new rates though technically we hve objected and has mail the management regarding the same . The mail is yet to be answered . Plz suggest something that the management agrees on the old terms n the deal gets completed successfully.
