I had one problem with them, they didn’t transfer my carry over from the old IOG.
But during the last 2 months I was receiving replies on my emails and I saw that they were working on my problem. Today finally I’ve received login details for my Party cashier account, so I hope to see my carry overs there soon, and I’ll again start promoting them. I was not sure in their responsibility when I didn’t see my carry overs and several months ago I currently stopped promoting them . But now I see everything will be ok
