Metro by T-Mobile review: Unauthorized charge

My husband called Metro to add hot spot to his phone. He was not told that he would be charged a $24 fee for doing this after the 1st of the month. Once we realized that our bill was higher than it was supposed to be I contacted support to find out why. The agent told me about the fee and that they would not reverse it, even though it had not been disclosed. They said a text had been sent stating the fee. Which is true, but should have been told him during the conversation and BEFORE making changes to the account. I have had conversations with Metro in the past and always found them very helpful, even if they are sometimes hard to understand. Anyway, these agents I dealt with today were nthing like any I've dealt with in the past. They were very rude and condescending. Ralph (agent number 42426) is the last one I dealt with. They told me they couldn't reverse the fee since it was "Legit" but they did offer to reinstate our old plan without the hotspot and return the fee that way. I had to check with my husband about this. I checked with him and recontacted chat. I was then told by Ralph that he did not say this. I wish I would have taken a screen shot, I almost did. Very very disappointed Metro.
