Received Payment?

Hello, I've been trying to speak with a live agent regarding my payment that was mailed on January 24, 2026 in the amount of $236.67 with Check Number: XX53. It hasn't posted to my account; however I don't want my services interrupted as it hasn't been posted yet. I tried to schedule a call back since it said that it was a high request volume or something like that. It was giving me a call back for Friday. I need to confirm today that my account will be noted that payment was mailed. The chat kept telling me to make a payment or gave payment option to make last due balance which is what was mailed in. Please advise on how I can get this taken care of and in the event that this happens again, am I to jump through hoops like this?  On my last attempt by phone, it said that due to security reasons, I would have to discuss my account online. So, here I am.
