Wifi pass

I ordered wifi pass for $10 yesterday,  understanding that it was for new customers who don't have internet through xfinity. After I signed up and they took my money, I wanted to ask a question about how do I login with a different device. I called customer service and they asked me for my zip code and address.  I told them and he kept saying it's not coming up that 8 even have an xfinity account.  I told him the6 took the money, and that I've been using the wifi all day. He looked and looked to find my account 9r soneth8ng that says I'm a customer of wifi pass. He just played stupid, so I ended the call. This guy didn't even know any details of what we were talking about. I then asked if somehow I had to already have an xfinity internet account.  He didn't know. Does anyone know how wifi pass works? I thought it was for people who just wanted to get on the internet for a cheap price. It says for new customers only for the $10 promotion.  Someone please be smarter then the guy that works for xfinity, and help me figure this out. I'm sick of companies making mistakes,  then I have to suffer for it. Not happy with the customer service at all.
