breach of contract

I am seriously disgusted, I opened an account by Joshua Doore, I purchased some furniture and it was delivered and I was very happy about the service that I received. That is until today I was told by someone who has no right to know about my account as one they have not signed for it it is not in their name, two they do not work for the company therefore should not be told any details regarding my account, that the person who handled my purchase was braging by them about how much debt they got me into and how much they got me to spend and buy, this to me is a serious breach of contract as my privacy as a client should be protected and not discussed with anyone except me. I will take this matter further if I don't get results as this is not the way that business should be conducted.
