Product: Credit card

Home Depot Credit Services continues to claim I am responsible for an overcharge of {$300000.00} despite multiple attempts since XX/XX/XXXX to provide documentation and evidence to the contrary. The full dispute is as follows : On XX/XX/XXXX, a contract for a fence installation was signed with Home Depot for the total amount of {$6000.00}. This was to be in two installments- one for {$3000.00} and the second for {$3000.00}. 
As evidenced by my credit card statements with a closing date of XX/XX/XXXX, both installments were charged to my Home Depot Credit card on XX/XX/XXXX. XXXX charge for {$3000.00} on XX/XX/XXXX and then again for {$3000.00} on XX/XX/XXXX. 
These charges remained on the card statements and were never removed as evidenced in the statements for XX/XX/XXXX, XX/XX/XXXX, XX/XX/XXXX, XX/XX/XXXX, XX/XX/XXXX, and XX/XX/XXXX. 
A third charge was then later added on XX/XX/XXXX again for the same amount of {$3000.00} as shown on the statement ending on XX/XX/XXXX. This charge was extra and above the two charges on XX/XX/XXXX. 
In XX/XX/XXXX, I notified Home Depot of the extra charge assuming it was fraud. Home Depot temporarily removed the charge but then added it back to the account when they found no evidence of fraud. 
In XX/XX/XXXX, I fully paid for the two charges from XX/XX/XXXX, however the overcharge from XX/XX/XXXX remained on the card. 
After providing ample evidence and documentation of the charges and the contract amount to Home Depot Credit Card Services, in XX/XX/XXXX they removed the XX/XX/XXXX charge and considered the matter resolved. 
I then closed the account on XX/XX/XXXX. However, on XX/XX/XXXX, the charge from XX/XX/XXXX was AGAIN added back to the account, this time with accrued interest. Again, I attempted to call and email Home Depot Credit Card Services, Home Depot Customer Service, and the local Home Depot Store. Instead, I received a letter saying they stand by their decision and that I am fully responsible for the overcharge of {$3000.00}. 

In XX/XX/XXXX, I spoke with the Home Depot Store in XXXX, VA and with Home Depot Customer Service and they are unable to view the second charge on XX/XX/XXXX in the amount of {$3000.00}. For this reason, they charged the credit card again on XX/XX/XXXX for the same amount of {$3000.00} and continue to claim that I owe the amount, despite the fact that I have already paid the full contract amount of {$6000.00}.
