Due to the timing of some changes to my account, last month's bill was overstated by $100. I called (before the strike) and was told that the credits were pending and that I shouldn't pay this bill. I have autopay so the rep checked and told me that a lesser amount would be paid. Well, nothing was paid. I got my next bill will the corrections, but showing that the previous balance was overdue. After the credits I owed $22, which I paid immediately because Verizon was showing that my account was overdue. Then I tried to cancel autopay, but the website has some issue and tells me that I should try again later. I've tried several times over the last two weeks with no success.
My question is: If you have autopay, but you make a payment, does the system know to deduct your payment from the balance due or does it just automatically pay the amount of the bill?
