Phrecia - Currency Exchange

I have kind of a big problem.

Back in phrecia, I listed an omen on currency exchance. However, I've never retrieved it. I also made the AWESOME decision of trying to delete my phrecia character to solve this (because i have never used migrate button before and I was afraid something bad would happen).

Result: I have an order from phrecia on my currency exchance and I cant remove it - And the limit of 10 listings on the currency exchange is account-wide, which means I no longer have 10 slots for listing, but only 9.

Please help me fix this. I don't care about the Phrecia character nor the omen, I dont want them back, I just want my 10th listing slot back.
