Thank you for arranging a nice servicing team to attend to our unit yesterday. They have done a good job and we are happy to pay/sign the contract (3times/year)with you. I trust you have received the cheque from the team leader and would appreciate if you could acknowledge the receipt of the payment.

For the 2nd servicing, I will inform you well in advance once we known of the available date, probably, in mid August. I hope it is alright for you.
Thank you and have a good day ahead.
