Check the date last week he sent you payment then talk. He already got funds but taking his own time to pay members. Don't support just because you're in the signature campaign.
The delayed payment for week 2 was because Madz only had one week's worth of payments in the escrow wallet. The money was sent a little late to Madz, but then the payments were issued within days. As well, Madz then payed the week 3 out very quickly. Rounds were supposed to end on Sunday but the dates got confused, so I imagine Madz is busy during the regular week and the one day he had time (he checks every user individually every post) is not when the round ends.
The last part about Madz schedule is just what I assume but the rest is fact about payments to the escrow wallet etc.
