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

From : XXXX XXXX Address on file XXXX XXXX XXXX, XXXX, XXXX XXXX Previous Card Number before it was replaced was XXXX XXXX XXXX XXXX I am in need of help. i purchased a item off of XXXX  and used my ATT Universal card to pay for the item via XXXX. The transaction was authorized by me for the amount of XXXX $ for a watch. 
XXXX order number is XXXX and it was sold by XXXX id XXXX and title of the item is XXXX XXXX Submariner Ceramic Two Tone XXXX XXXX Dial XXXX Men 's Watch. The XXXX   item number is XXXX XXXX date of XX/XX/XXXX. 
I paid using my Attuniversal card via XXXX. I never received my item from the seller. The tracking number they provided shows clearly the item was sent somewhere else and signed for by someone but not to my physical address. I never recieved anything at my address and nor did i sign for anything and believe it is fraud. The seller never responded. 
The seller never responded to numerous emails that I sent via XXXX. It was then i contacted ATTUniversal card. The person who took my call must have misunderstood me and opened a case of fraudulent charge that i did not authorize. But I did authorize the charge but I never recieved the item. 
I even called the next day and spoke to another agent at ATTuniversal and they said that I did a good thing of calling as the case only showed that a fraudulent charge was made. 
The agent stated that he was able to add notes to the current case and that things should resolve soon. Sadly, that is not what happened. I was never contacted about anything in regards to the situation by ATTuniversl citi cards. I simply got a Letter via online that stated against me but was a little confusing. So i called ATTuniversal again and they said nothing to worry, they have agreed in my favor. i was relieved to hear that. But later, i saw the charge was added to my billing in the amount of XXXX . Clearly there has been a mistake. I have already contacted ATTuniversal Citi and also XXXX. They have stated that the case is ongoing but what I do not see that anywhere on my acct on ATTuniversal citi nor XXXX but i was told the case is open and the merchant has been contacted. I must have made about 30 calls to XXXX and attuniversal citi cards regarding this matter. They should have a record of all calls and also recordings. 

If you simply look at the tracking the Seller has provided, you will see that the item never was sent to me. It is a XXXX tracking number of XXXX that the seller provided to XXXX. When i clicked on it, it showed the item was already delivered and signed for on XX/XX/XXXX ... .that is before I even bought the item!. 
The XXXX listing is XX/XX/XXXX but delivery shows XX/XX/XXXX? to XXXX XXXX, XXXX .... I am in XXXX. not in XXXX. Once again, item bought XX/XX/XXXX but delivered XX/XX/XXXX? how can that be? and delivered to XXXX  where the item was supposedly coming from. I am in XXXX  my whole life. 
I have copies of all that i could gather to show proof of the fraud that this seller has done. I even mailed it to the Citi cards via certified mail and also to XXXX but to no avail did I get a response. I am so disappointed about how long this is taking but i believe once the respected merchant see 's this, they will conclude what has taken place. Thank you for your time and I hope to hear from you asap to close the matter. I have been a faithful citi card customer and XXXX customer for years. thank you for hearing my plea and request. 
XXXX XXXX. 
you can call me XXXX XXXX email XXXX XXXX
