Product: Credit card

So I had lost my card on vacation ( which I was unaware of ) and the next day in my emails I was getting all these charges from some XXXX XXXX place. I immediately called Chase and they cancelled my card. So they refunded me the money and about 1 month later, I got a letter saying they decided in the merchants favor. I again immediately called Chase and explained that these were not made by me and how could they decide in merchants favor? They told me the email address used for the account matched XXXX  account. I explained I could go online and find pretty much anyones email address. Mine is all over the internet for my job. So they said they would reopen the case. Mind you this is a total of {$1400.00}! XXXX different transactions. Well I just got a call from a rude gentleman at Chase that called me from XXXX ( XXXX ) XXXX. I wish I recorded this call. I explained Ive never been on this website. I also did research showing this XXXX company has scammed hundreds of people with the same thing! Then I told him Im actually in the bankcard business. I setup businesses with credit/debit machines. They get disputes all the time. For instance, I have a guy with a pizza place that in a span of 2 month had a lady who disputed 4 different orders she received from this pizza place. He has her on camera, has signed receipts, and if the food is no good why would she come back after the first time? Well guess what. The little guy like him loses the dispute even though its total fraud. And here I have some overseas company that I never made a purchase with and I lose {$1400.00}. Back to the gentleman on the phone. He said my only option is to get ahold of the company XXXX and work it out with them. I told him I think thats his job? Ive tried numerous emails to this company XXXX and they dont have a phone number to call. So therefor how can I do anything more about the matter?? I was appalled at the guy at Chases tone with me. He didnt want to help me at all. He said, sir, these charges will remain on your account and hung up. So much for them investigating further into it. He told me XXXX said it matched my IP address? I explained thats not possible. And even so, they just take XXXX word that it actually matches my IP address?? And thats it? I will turn my phone over to any investigator and prove nothing was ever done on my phone with XXXX XXXX  besides doing research on them after this problem. Please help me and let me know what information you need to try and help me get this resolved. I assume youll need a cc number or something. Thanks and I hope to hear back about this soon bc I cant afford this {$1400.00}. One last thing. There was actually XXXX charges and XXXX had proof of XXXX of them. So the only charge they arent making me pay is 1 of them for {$50.00}. I questioned that also. If it really was legit, why did they not have proof of the {$50.00} charge?? Please please help me with this. Thank you So I just cancelled my case because I found out a big piece of information I needed to add. I actually went to XXXX website and tried to login under MY email address of XXXX, and it said there is no account with that email! So therefore if I really did purchase anything on their website, this proves they are lying because I dont even have an account with them! I felt I needed to add this after I just found this out. Thank you
