I set up a withdrawal on 5/31/2016 and it's now 7/11/16 and I still haven't been paid. I've emailed back and forth with the finance department and they said I should be getting my money soon. My withdrawal request has been "in progress" for well over a week now.
Taken from the Slots Plus website: "Your request is 'In Progress' and our team is awaiting confirmation from the payment processor regarding the fulfilment of your request. Normally, your request will not be in this state for more than a few minutes."
It's been a lot more than a few minutes. I tried emailing Slots Plus again today and now they're not even bothering replying to my email.
