Product: Checking or savings account

I deposited a check on Sunday, XX/XX/2022 at the atm location, XXXX XXXX XXXXXXXX XXXX XXXXXXXX, XXXX, TX. This is the atm located at my banks main office. According to the atm my funds would be available to me Tuesday, XX/XX/2022. This made sense to me since my original terms and conditions confirm that any personal checks written from another bank would be deposited on the business day after they were deposited into the bank. When I checked my balance on XX/XX/2022 my leger showed the funds had in fact been deposited but were not available to me to spend. I went to my local branch and spoke to an associate in the drive through she stated I would need to call the back office. She also told me that funds deposited into the atm took longer and encouraged me to deposit with a teller next time. I called the " back office '' number I was given the lady I spoke to on the phone explained to me that my funds had been placed under hold. When asked why she explained it was due to the amount of the check. According to my original terms and conditions as long as the check is not " equal or exceed XXXX '' then it would be the standard 24-hour hold. The check I deposited was XXXX. I asked to speak with a supervisor. I was told there were none available and that she would have someone call me whenever they were available. I waited after the call and got no call back I decided maybe I could talk to a manager at the bank to get something done. I went to the bank and was told there were no supervisors at the bank. They were on vacation but I could talk to a banker. I brought my original terms and conditions with me and spoke to the banker. She explained to me that the reason my funds were being held is that they were unsure if the other bank would honor the funds. The funds were already showing out of the other person 's account and in mine. I confirmed this with the person that had written the check. I explained to the banker that the funds were showing in my account and that I had spoken to the other person involved and the funds had already been taken. She then told me that despite them having the check and pulling the money from the other account they could not confirm if the funds had been taken yet so therefore could not make my funds available. She also mentioned next time I should use a teller for a faster deposit time. I left the bank location and came back home to wait for the call from the supervisor early in the morning. At XXXXXXXX XXXX after attempting to get an answer all day and waiting for a call I decided to advance in filling complaints and needed the FDIC number from the bank to lodge a complaint I called the " back office '' number again where I was reassured that eventually I would receive a call from a supervisor and told they had no idea what their FDIC number was. I believe PNC has violated Appendix C to Part 229 C-4 of 6500-Consumer Protection, Under laws, regulations, and related acts. According to this section of the FDIC federal laws and codes, the check should have cleared in 24 hours. Both banks were local banks and the check was not over the specified amount. I believe I am being penalized for using the atm since both of the employees at the physical bank mentioned I should have used a teller.
