Approx 5th October (sic), maybe a day or two later.
Your current balance, if over $100, up to 31st October will disappear around 5th November, give or take, but earnings from 1st Nov onwards will still be shown as your balance for November.
Your October earnings (if over $100) (i.e. Oct credit sales and Sept subs and GI) should be paid on 23rd November.
