I can read your urgent mind,but I need to comply with the rules of my company.
I hope to sovle the present problem asap,but I can not determine it by myself,it is out of my control.There are many different departments in my company,and what they do should comply with the regulations.Now the problem is that we are unable to modify the B/L unless we receive the total amount,which I have told you many times.Therefore,I push you to remit asap.Actually,we spared every effort to solve this problem.
