The question is have you earn any affiliate rewards in the past if the answer is yes then it mean their trying to put of something that may end up as being a deduction or reduction pf the percentage payment,  which will result in you getting a smaller amount as your reward for this round.

But is this is your first time to get the reward and trying to know what you total amount in rewards are,  it then means you will need to keep following the support and create reminder so that if their is a problem from your own end you can resolve it because at this point if I am right you don't know the exact amount your affiliate reward will be unless of you already made a manual calculation of that which is almost impossible so you have really keep in touch to get what you have to do to get your rewards credited.
