Very strange.
The wrote "After careful consideration, we regret to inform you that we will be closing the Tote Ireland affiliate programme on January 31st, 2019", but the signup form on totepartners.com is still working?
And they also wrote "Outstanding commissions will be paid out from the last payment cycle up to January 2019 inclusively.", but they didn't pay yet?
Yes, if the outstanding amount is significant, and/or if you find someone to join you, why not take legal action... Good luck!
"Semper paratus!"
