I delivered order 2 days before delivery time. After 1 day buyer put on revision saying he needs 2-3 days to test. Today i asked him about testing and he said he shall check on monday. Order time is remaining only 6 hours. After 6 hours it shall show late on countdown but buyer shall test it on monday and today is saturday. Shall this lateness affect my account.
I need your suggestions and want to know your experience if have faced such situation.
