Wells Fargo is the WORST BANK, How could they put something

About 2 years ago I went into a furniture store to find a bed and saw one on sale, I spoke to the guy at the furniture store and he said that he would find out if I had credit to purchase the bed. He told me later that it was wells fargo national bank that his store goes thru to see if a person has credit and wells fargo denied me. Now they have that on my credit report even though I did not purchase the bed but was added to my credit report. No money or furniture was involved but still they have it on my credit report. Why would they add that to my credit score when I never borrowed money from them meaning the wells fargo bank. It is ruining my credit, please help me to find out how to remove them from my credit report when they should have never done what they did to me. I hate that bank so much I had my car through there and my car is fully paid off now. I would NEVER EVER go through that rip off bank again. They are only theives to the consumer and they don't care about helping. But having that on my credit report is pissing me off!!!
