Metro by T-Mobile complaint: Lied to.

Hi, I reached out to Metro pcs.
And spoke to someone via Internet about getting phone service and new phone. I told them I had a budget of around 25 to 30 a month. I asked about there new advertised 25$ plan. She told me about it and recommended this 40$ plan that was new. And the best part they said was I get a discounted phone and on my second payment make sure to use auto pay. So you can get 5$ off your bill and use it again on 3rd payment. Bringing your 40$ bill down to 30. They said that’s in your range as well correct. I said yes but is this how it will happen because I had Metro years ago and was duped by the lady at the Metro store. They said just make sure to auto pay on the second payment and 3rd. So last night I tried to figure it out and couldn’t. So I contacted metro chat through app. And spoke with a agent I have his name and id number. And he said that is the policy but only for our now evergreen plans of 35$ up to 65$ plans. So I said ok why doesn’t mine fit in for auto pay when I was told and coached to a higher plan that I specifically told them I couldn’t afford unless the autopay would be no issue. He said no you can switch to one of evergreen plans. I asked about the 35$ which said 5 GB of data a month. 45$ 10gb a month data. I said no my plan is for unlimited. He said that doesn’t have the autopay. So I asked for supervisor. He took some time and came back and said this is a supervisor Michelle I have her id number as well. She said MY agent already told you that the plan you have doesnt have the 5$ autopsy. I asked her why was I told that and how would I know all this about these plans if I didn’t speak to someone. She said where online or store. I said online she said no we don’t have anything to do with autopsy on that plan. I said I would contact bbb and corporate. She was very rude and I can’t believe metro tells people whatever they have to in order to sell higher plan lie to customer and don’t even care. I want what I was promised. This isn’t fair.
