USA Benefits $100 gift card, had me sign up for many 30 day trials. Luckily there's no $ on card and I'm canceling it. Internet

Recieved postcard in mail stating Im eligible for a $100 Walmart gift card. I called the # and spoke with Jason Parker ID #12149 (he claims). I was told there are no strings attached other than $6.95 to have it mailed to me. I told him I don't have any money on my card. He said that's ok he will run it when there is money on it. So I get transferred to someone who is rude and pushy telling me not to talk for 40-60 seconds while he starts the recording. The recording starts and I repeat my info for some monthly trails all for a monthly fee. I said "no" to the recording, dude comes back on the phone upset with me for saying no and now we have to start the recording all over again. I told him "you guys are nuts". He reminds me of how I want my gift card and all I have to do is be a smart customer and say yes to all the offers. So I play along and say yes to 4 offers all the while repeating my card info and stuff. The next offer is like $30 a month so I said no to the recording and hung up. A minute later an unknown number calls at 11 pm. I ignore it while making a note to myself to crawl to my bank apologizing for being a fool and to please cancel my card and issue a new one. 

Thank you for letting me vent.
