Complaint Review: Tashana -USA Benefits

I was calling to Discover credit card customer service and I messed up a digit and I landed up calling a company called USA Benefits. A lady called Tashina was started giving details about the offer and was so eager to get my card details. During the call I didn't realize that it is a phishing company, I was in the mindset that they some parallel company to Discover. I gave her my details and asked for the customer service numbers to get help in future/to cancel the offer. She gave me 2 numbers and I asked her whether I am going to get a mail regading this offer or not. She said yes, I will be getting a mail from them but I didn't recieved any mail from them in next 24hours and that made me look about this company on internet. I found some scam post with this companies name. I called the same number again to cancel me order and fortunately the same lady picked my call. I told her that I am calling second time on this number and I didn't recieved any mail from them but she again started asking about my details to sell the same 100$ offer. I told her that your system already have my details but she said she was unable to find it( I am pretty sure that they are having my details because wheh the first time I called her she was asking my details very slowly and repeating it for confirmation. ). By this time I understand that they are not real and I blocked my card. I thought blocking my card was a better option instead of cancelling my order. 

If someone here is going to take on this people I have the number on which I called and the other numbers that they gave me as their customer service number. One more think I want to add, everytime I call that number I get new offers from them.
