Welcome to the Community Forums @LaysaBrunet.
I'm with @goblin. I cannot understand your question clearly?
You title reads "I was blocked from talking to vendors".
Unless you are seeing some kind of error code, it's most likely they are blocking you.
Are you making lowball offers? People get annoyed and will block you.
If your using cut and paste in replies, you'll get an error code and instruct you to go and revue the community guidelines. I believe you would need to do that to get a reset.
Please, clarify your comments so we can understand fully.
