Today morning, when I wake up, I got a surprise from Fiverr. I had a notification message. When I opened it, it said, your order with (Buyer) has been cancelled. (mutually cancelled).
Interesting thing was, that this order had been delivered/marked completed 2 months ago. The buyer had accepted the delivery, you may see his review about me.
Another interesting thing about this order is, the buyer has given me a tip also for the order.
