To ensure clarity around affiliate payments I followed up with the company that holds the casino license for the former Absolute Slots and current Slot Power. They've stated that they will be responsible for paying all affiliate commissions, including anything from before the recent changes as well.
Here is the statement from Charlie:
He clarified that the financial partner referenced in the above statement is Comhill Corp. ("Yes absolutely correct, Comhill Corp are the financial partners.")Fatinovia Holding of Cyprus operates Slot Power. The financial partner of this company is responsible for paying affiliate commissions for Absolute Slots up to and including April 2009, and for all future Slot Power affiliate commissions from April 2009 onwards.
As far as they're aware, and as far as I'm aware, there is only one case where it looks like an affiliate payment may not have come through and the webmaster in that case is in contact with Slot Power. If there are any other cases please get in touch with them at affiliate AT slotpower DOT com, and feel free to CC me at steven -AT- gpwa -DOT- o rg.
