I have checked all the details & due to misunderstanding between Ebro & Duflon wrong parts have been manufactured.
We manufactured single part & now we need to manufacturer 5 different ring, the cost of part will increase due to increase in charged weight & machining cost.
Please refer attached your order no 760884 wherein I have mentioned new prices based on increased charge weight & machining cost as we need to manufacture 5 different ring to supply one part to you, request you to accept our price & send amened order across.
I will instruct my factory to manufacture & supply part in shortest period of time.
