Marriott International  -  Multiple billing issues

I have been in dispute on two separate occasions prior to the third situation arising with the Courtyard Marriott located in Plano Texas at Legacy Park. I check out of this location back in April 2021 and on June 2 of 2021 I had a payment of $393 the duct and from my credit card which is what it was for a week right at that particular location. This bill was paid in full detect it from my account on for 2021 and after multiple attempts to try to get the money refunded and a useless call with the Marriott elite customer service Department I am at my wits end right now because this red money still has not been refunded today as of June 10, 2021 this company has overcharged my card on three separate occasions and this charge was without warrant without notice and is now being ignored by my request for a bill and a reversal of discharge. I have sent all of the required documentation showing the deduction from my bank accountThat the bill was paid back in April 20 21 and I'm not getting any help from any side the hotel has not responded to my communications in a request for my folio which was promised to me and I don't even know what they were trying to charge me for I have no receipt I have no idea the hotel is very withholding of information and not quick to respond. I believe that this location is a franchise not a corporate location but they should still be held under the same rules by using the name
