Sale of false contract

I wanted too upgrade my account ,my data bundle account I had a 3 gig that was uncapped at an fix rate.when wanted too upgrade I had an verbal agreement with a sale consultant that I would get an 5 gig uncapped at a fix rate no extra charges I could not have sign on the they because they never had stock when I went back when they received stock I wanted to sign the that Deal that we agreed too after I sign I just wanted too make sure its the same Deal that we agreed on then she told me no only 5 gig day and 5 gig night when I said no this is not what I agreed too she told me that the other sales consultant did not explain incorrectly and the I told her I wanted too go back to my old contract she said no I can't go back and she didn't't't want too cancel my \new"contract. I am very unhappy with the contract that be sold too me under false believes. I just want what I was told that's all or I am going to an other network. Why would I to settle for a contract that not better then the one I had that was uncapped too one that limited??? And then 4 hours they suspend my account I Lost 3 days of work on my phone unacceptable """
