Past Balance

Hello,

So I missed last months payment and now I have an unpaid balance it says my service will be disconnected on Novemeber 11th so my question is do I have till the 11th to pay it? I'm asking because when I check the payment arrangement it says Nov. 6th so I'm worried that it's due the 6th which I can't gurantee I can pay it by then I did just start a new job this  week  I'm thinking I should have money to pay it on like the 10th of course this is me assuming how much my paycheck will be so it could be more or less. If I can't pay it will there be any way to extend it? 

Thanks
