Product: Credit card or prepaid card

I opened this rewards credit card account with Capital One in XXXX of 2022. I opened it specifically for everyday purchases that I was making on my debit card. I was only given a {$300.00} credit limit so I am forced to make payments often in order to utilize my card for my everyday spending. I typically pay the balance daily. From XX/XX/2022 until XX/XX/2022, I did this from my debit card without issue. The payments were applied and immediately applied to my available credit for immediate use. XXXX separate payments ranging from the amount of {$10.00} to {$140.00} were all made using the same debit card. Each of these XXXX payments were applied immediately and for each I had immediate access in my available credit. On XX/XX/XXXX, I made my first payment over {$200.00} using the same method as before, my debit card. The payment wasn't applied to my available credit and I received an email asking that I contact them regarding the payment. I called them and was asked to verify each payment made as payments made by me. I verified each payment. The agent then conferenced in a customer service agent from my bank and confirmed that it was my account and debit card in which I was making the payments from. I was advised that all restrictions were removed from my account and I would have no further issues. From that point on, I made an additional XXXX payments. Those payments took XXXX hours to be available to me in my available credit. Frustrating but I didn't make a big deal about it. Yesterday, XX/XX/2022, I logged in to make my payment. I made a payment of {$240.00} using the exact same debit card that I had used with every other payment. The same debit card that the agent called my bank to verify was my debit card. I logged in today to see that my available credit is {$0.00}. I called and I am told that there is a hold on that payment until XX/XX/2022. I do not have access to the payment that I made with my debit card for TWENTY-SIX days. I asked to speak to a manager as this hold doesn't make sense to me. I was transferred to a Fraud Account Manager who advise the same. She stated that it is a system hold and they will not remove it until XX/XX/2022. I asked why that hold would be placed and she stated that it could be due to unusual activity. I advised that this isn't unusual activity. I have paid the nearly daily from the same account since opening it. I asked to speak to someone else who could provide resolution and my request was denied. I asked for contact information of someone who could provide me more details and assist with my concern. My request was denied and I was advised by this manager that she couldn't help me any further and that she would be ending the call. She was hanging up on me and refusing to assist or get me to someone who could provide any resolution. This is a debit card payment that has already been taken from my bank account. The same bank account that I confirmed with the agent as legitimate and mine on XX/XX/XXXX. Each time I make a payment greater than {$200.00} there is an issue and my account is held. I can understand if there was concern and they needed to contact the bank or even wait until the payment posted to my account but to hold a payment for twenty-six days is abusing their power as they will have the funds from the payment long before that time. I am being punished for making timely payments and not holding a balance on my credit card.
