It will take a while to explain the entire situation, but the gist is as follows:
Client asks to cancel order before any delivery is made, no justification.
I contact cs, say I don't want to be affected.
After a lot of back and forth (the first agent was a bot, as always with CS), they confirm both my cancelation rate and success score will not be affected in any way, and that CS can manually fix both.
I cancel. Cancelation rate is fixed, 100%.
Success Score of the gig in question starts showing "Cancelations" as strong negative impact, when it didn't before.
I contact CS asking wtf.
CS now says "the system just needs a little more time to update and shows this accurately, blablabla, success score is stable, won't affect you much, etc."
It's now about 7 days after the cancelation. Still showing as strong negative impact. It's the only cancelation we ever had on that gig.
Either they were lying before, or they lied now. Either they can fix it manually, which means it should go away, or they can't, they lied about it, and they are waiting for it to go away on its own.
