Complaint sub-issue: Credit card company isn't resolving a dispute about a purchase on your statement

On XX/XX/2022, I placed an online order with XXXX XXXX which included XXXX items : Bathroom faucet @ {$36.00}, gas range stove @ {$510.00}, ( XXXX ) over the range microwave @ {$210.00}, Refrigerator @ {$960.00}, electric dryer @ {$560.00}, Top load washer @ {$480.00} drop-in kitchen sink @ {$270.00}. The total amount for this order was {$3200.00}. On XX/XX/2022, one item ( drop-in kitchen sink @ {$270.00} ) was canceled and the credit was issued. Therefore the total for my order of now 7 items was {$2900.00}. I placed another online order for the same drop-in sink on XX/XX/2022 after being notified that item was canceled. Even though this item was an online order I opted to pickup item in-store. My card was charged for the {$270.00}. On XX/XX/2022 the bathroom faucet was delivered. On XX/XX/2022 5 items were delivered : refrigerator, stove, washer, dryer and 1 ( one ) microwave. There should have been two microwaves delivered. The delivery driver put a note on the delivery form stating one of the microwaves weren't delivered and that out of the 4 items on that particular delivery form ( the remaining two out of the six items being delivered ( washer and dryer ) were on another delivery form ) only XXXX parts were delivered. The second microwave was not delivered. The delivery person took photos of ALL items that were delivered. I immediately contacted home depot to inform them that I did not receive one of my microwaves via text. They stated they would do an investigation and would have to contact the delivery company to find the item. Several days have went by and I didn't hear from them, so each time I contacted them they would tell me they were waiting for a response from the supervisor of the delivery company. On XX/XX/2022, when i contacted home depot they stated they see the item was not delivered from the pictures and the note the delivery person left and that they would send out a new microwave with a delivery date of XXXX XXXX. They also had to reach out to XXXX ( the manufacturing company of the microwave ) in order to get the item re-delivered. XX/XX/2022 came and NO DELIVERY or even A CONFIRMATION of delivery. By the time XXXX XXXX came around and they again acted as if they didn't know what was going on and acted like they gave me a credit of {$270.00} already. The credit for {$270.00} was for the cancellation of the DROP-IN SINK. The amount of the microwave was for {$210.00}. They never credited me for the microwave that I never received and still keep insisting that they did issue the credit when they didn't. This transaction was on my XXXX card ending in XXXX in which XXXX sided with the company over their long standing customer without even getting any documentation from me to back my claim up. I contacted XXXX on XX/XX/2022 to open this dispute since XXXX XXXX keeps giving me the run around. XXXX has shown numerous occasions how shady they can be. Especially to a customer that has NEVER had to file a dispute on this credit card account since I've been with them. XXXX came up with this decision in a matter of 3 days. Not only have XXXX XXXX has caused me XXXX XXXX, and caused my account balance to reflect an incorrect balance for nearly 2 months now ruining my credit reputation, but XXXX as well. I have not only the delivery receipt stating the microwave wasn't delivered but the original text when dated back from XX/XX/XXXX when the other items were delivered informing home depot that XXXX of my items weren't delivered. AS WELL AS ALL PHONE RECORDINGS FROM ALL CONTACT WITH XXXX XXXXXXXX XXXX XXXX can listen to the call to me on XX/XX/2022 @ XXXX for 47 mins of their customer service representative canceling the microwave re-delivery and them attempting to issue me a credit.
