Can someone help me with how the billing timeline works? I signed up for 5G service on 1/1/24. I then completed my auto-pay settings on 1/14/24 and saw I had $80 due which I paid assuming it would cover January. I then had $80 auto debited on 1/16/24, with no auto pay discount applied (though that's a separate issue). My question is did I prepay for February? I've had the service two weeks and I've paid for two months already?!? Is that mid month payment taken to pay for the upcoming month or the previous month?
