Agents are horrendous

I was offered a deal that would provide me with a free iPad and no mobile line the agent who set this up lied to me and activated a line so now my bill is high I called the mobile side the first agent told me it was the internet side who did this to me and transferred me to Xfinity Internet line, I talked to Tiffany who from off the bat had an attitude and you can tell she doesn't like her job, she was not helpful and was hesitant to transfer me to a supervisor when I finally got the supervisor she was also rude and not helpful when I kept telling her my issues all she kept say was if I wanted to cancel, no I wanted my issues resolved her name was Stephanie, she shouldn't be allowed to be a supervisor if she can't do simple customer service, finally asked her to transfer me back to mobile she continued to keep talking after I had already asked to be transferred finally got Mike who I know is not in the U.S. but did an amazing job of explaining my Internet and what happened to the original order that was done to my account he was able to give me a one time credit on my bill and took his time explaining everything even when it was not his department ( internet) something that the Tiffany and Stephanie couldn't do. And then I let his supervisor Adam know that he has a good employee and he was helpful. But because of the first interaction I will never refer anyone to Xfinity.
