Fake and deceptive t mobile promotion

Same thing happened to me One of the agents Gave me deceiving and misinformation. I called today and tried to get help and they told me there was nothing to do. I'm gonna make a complaint to bb. This is Ridiculous T-Mobile really needs to get it together. I was told that I would get gift cards for joining there internet I received one but was still waiting on the other one.  I called to check and this supervisor tell me that I was given Misleading information. Well if that the case I would expect them to make it right . He said there is nothing he can do. I felt like the lady did anything to try to sell. Which that's not right for someone to do that. Not to mention I had to go through all this kinds of mess with the Internet when it dropped and I had to go in and take Box because it stopped working because of an update. I was out of internet for 3 days. I would have warm people Not to believe T mobile says when you're switching over.
