Work place situation!

So I work for one of the biggest known banks (not gonna say names) & ive been there for about a year & a half. We got a new manager & supervisor about 5 or so months ago. I'm very cool with them we talk about work stuff & they gives me advice like how to hit my sales etc. but now 2 COWORKERS tell me that BOTH the manager & supervisor has been talking about me. They say they'll never promote me & that I've burnt bridges with them & im not good for the company but they haven't told me. IVE NEVER DONE ANYTHING TO THEM. I hit my sales goals I work over my scheduled hours, I've never gotten into any arguments with them. And one of my coworkers who's only been there 3 months is telling me that they are going to give her the promotion that they have PROMISED me. I don't know what I've done. What do I do? They're telling my coworkers things about me and they are supposed to be managers and come to me!
