Partial Rewards Payment Only - Still Owed BAT

I have finally received a payment from Brave (month of April) but only a small percentage of what they owe me (still waiting for February & March). I’m still owed over 14 BAT. So clearly the problem is not Uphold, who provide a good service. All I want is what I’ve earned, all I want is what I’m owed. Now that I know a payment can be effected, I want what’s rightfully mine. Please fix this issue ASAP. Thank you.
