I have spotted many bugs on the fiverr site, but this one it affects my rating …
I was creating a offer of one of my gig with 3 days delivery. This at a late hour of 27 February, the due date of the order (as shown by fiverr) was 3 March (as if the weekdays were not calculated).
Since then the countdown has never stopped and now, on Sunday, the delivery date has arrived.
There is not much to debate. bug
in any case from now on I will consider the weekdays in the orders delivery time (the situation here not seems be much responsive, at least not by fiverr)
