Product: Credit card

I got in the mail a XXXX credit card that I never signed up for. And it said to activate it, and when I tried to activate it when I received it the letter it said the card couldn't be activated because a different card was already activated but I never signed up for anything but they sent me a card that wasn't even functional and I've never even used it once but they're sending me in the mail of bill for over {$3000.00} and this is after they said they canceled that card they sent me a letter saying they canceled the account if the account was closed and canceled and I've never used the account or ever signed up for one then how do I have a bill for {$3000.00}? Did they give a card out to someone else that stole my identity? Because I've never used any card from them. I never signed up for anything through them and it seems like they put fraudulent charges on my account because I've never even used a concora credit card. And I've also done research about them a couple months ago and saw a lot of bad reviews but I've never signed up for any credit card through them and they've never even sent me a credit card that was functional so I don't know how I have a {$3000.00} bill when I haven't used any of their credit cards I haven't used a credit card in many years. And they never even sent me a working credit card to begin with so it seems like they're either scamming me or someone stole my identity and they gave a card out to someone that wasn't me but either way I'm not liable for these charges because I never used it any credit card through them I never signed up for a credit card through them so I don't know why they're sending me a huge bill when I haven't even used their credit services. But yet they sent me a card that didn't even work and then they sent me a letter saying that account was closed and I didn't get a bill and then out of nowhere they sent me a bill for {$3000.00} when I don't even have an open account with them and I never even signed up for any of their services so this is an outrage and if I have to I will take them to court and then sue them for fraud and then add on the four-time multiplier punitive damages because I'm not liable for a card I never even signed up for or used. I didn't even know there was an account open in my name because I didn't sign up for it and I never use any of their credit services so why are they asking me to pay a {$3000.00} bill for when I never even used any of their services? So either they're outright making up bogus fraudulent charges or someone else stole information from me and is committing identity fraud but you would think that the company would make sure that they don't give a card to someone else that isn't me but apparently they did. Because if they didn't then they're just making it up fictional charges and expecting me to pay them. I think it's more likely that someone stole my information to steal my identity, but you never know, reading the reviews I read about that company it wouldn't surprise me if they did just make up some bogus fraudulent charges but I believe I'm going to need to take them to court because I'm very upset if they just gave a credit card out to some stranger that just said they were me. Aren't they supposed to make sure that doesn't happen and check that they didn't give a card out to someone else? And I never even got a bill from them I have one letter but I don't have an itemized bill from them they just randomly just sent me a letter and said I have a XXXX something dollar balance ; but what were the purchases? Where does the {$3000.00} come from? Where were these purchases made what state were they in? How come I haven't received any bills before this? Why are they sending a huge bill to my address when it's obvious that those purchases weren't anywhere near me.
