Order Delivered byt yet to Complete...Buyer offline

[datareward]

Hi,
First instance for me…I have delivered my order within specified time and now awaiting Buyers acknowledgement. I am not expecting a 5 start or reviews etc.
I know order will mark Complete after 3 days of delivery. But my concern is…Buyer is offline past 2 days and if he/she comes back after few days requesting for some alteration / modification etc. Should I encourage?

Buyers cannot request modifications after an order is marked as Complete.
