Lost my payment!!

This has been a total nightmare I paid my At&t bill back on Nov 15th to turn around and have my account not credited with my payment and then a late fee added. So I called AT&T to find out why it was still showing I owed this bill so they said they would investigate it they gave me a confirmation and incident number said that someone would he contacting me within 3 to 5 business days and I would also get an email no email nobody contacted me so I called them back they said they could not find my payment whatsoever in the investigation I was floored and just couldn't believe it!! I mean when you make a payment you in trust that they know what they do with your money and here I was being treated like oh well we just don't know where your money's at so you owe this bill plus a late fee so I ended up having to pay the bill again or my services were going to get cut off so then I pulled a bank account statement that showed that the money had indeed been taken out of my account but instead of saying AT&T it's a DirecTV took my payment I don't even have TV service I have Wi-Fi service only that I run my fire stick off of so I called them back to get the rudest Rep ever that when I told him about my payment back in November the investigation the bank statement and who the payment went to when I don't have DirecTV services and only have AT&T Wi-Fi this rep went through every month of my bill all the way back to August and how much each bill was all the way through till December and I kept saying yes I know how much my bills were that's why I paid them that's not what I'm calling about I'm calling about my November payment that is lost and my bank statement saying DirecTV took it out so y'all need to get with DirecTV and find out why DirecTV took my payment for a TV service I don't even have when I call y'all to make my payment for an AT&T bill and I pay the exact amount I owe for my AT&T Wi-Fi I expect that's where my money's going and he just kept ma'am I'm trying to be professional I'm trying to let you know what your bill amounts were and why you owed the bills finally I got frustrated with him and said I knew what all my bills were that's why I paid all my bills and ended up having to pay the one bill twice that I didn't need him to go over the amounts in the dates and everything else I wanted to know where one Pacific payment was and why that payment went to DirecTV for a TV service I did not have and that it needed to be applied to my AT&T Wi-Fi service that it was supposed to go to that I do have and once again this (Edited per community guidelines) started going back to my bill dates and amounts again talking about frustrating so I finally said can you please just put on a supervisor I'm tired of going in circles about something that doesn't even pertain to what I'm calling about I'm not calling you about old bills and what they were charges for those are paid and done with I'm looking for one Pacific payment that is lost and not paid and taken by DirecTV for TV services that I do not have and the fact that I had to pay it twice now I want it pulled back from DirecTV and placed on two AT&T because I don't have DirecTV services I asked him to put me on a phone with a supervisor and he hung up on me!! Very unprofessional and frustrating because I felt like I was being sent all around in circles on purpose so that we didn't get to the point of where my payment was at all and the fact that you have to keep calling back and going through all this to get a representative even on the phone! Finally I called back again got a different Rep thank goodness he was nice and very helpful he took the $9.99 late fee off and gave me the information where to fax and email my bank statement to but the fact that I'm even going through this and now reading all the other comments makes me in fear that I'm never going to find or get back this payment even once I show that it was indeed taken from my bank and paid. The fact that I'm even having to go through this period is just crazy how does a company just lose your payment in the 1st place so very frustrating!
