I don’t know in which category I should ask this question, so I added it in suggestion box.
Recently one buyer ordered an extras with my basic gig(3 days for basic + 4 days for extras). Now he also added the option of extra fast delivery(I set 1 day for it). So I have to deliver the whole work of 7 days in just 1 day!
I think this should be (1 day because of EFD + 4 days for extras). Is there anything I can do for it?
