Dear Poornima, As discussed during our recent conversation, I want to confirm that the payment for the service will be completed before the end of next week. It is imperative that we activate the service without delay to avoid any disruptions in our operations. I must emphasize the importance of providing prior intimation before stopping the service, as it can adversely affect our business operations. Make a reply to client
