bill past due

Hi, just got an e-mail that states my bill is past due. It is due on 4/20/25. So how can it be past due? It does show 25.00 past due. But my bill shows 75.92 like always I have 25.00 creidts per month and it shows I used 2 out of 6 and this month using the 3rd. My bill was 100.92 and I mailed in 75.92 for 2/21/25 and that was for taking off the 25.00 creidt. My history shows you used the first 25.00 for the bill of 100.92 on 2/21/25. I don't know if I am miss understanding my payment history. My bill that I just mailed for 4/20/25 just shows I am due for a payment of 75.92. My invoice I got in the mail does not state any late fee.

I hope this gets sorted out. If I owe the past due of 25.00 add it to my invoice, I do not believe I do since you used my creidt. So that I can pay it. I don't look at my bill on computer unless there is a problem. Thank You, shadowwalker.2015
