receivable management grouop rmg collections never had an account or a credit card in 20 years. on my d**n credit report after trying to rebuild it columbus Georgia

 i checked my credit report at least 4 years ago and something from receivable management group was on there. i called them and spoke with someone. they told me to email them a dispute and i did so. i do not purchase cds and have not had a credit or debit card to do so. i have a charge of 144 on my credit report and i refuse to pay for something i never purchased. i have told them before that did not live at the address where the merchandise was supposingly purchased and moved to another city. i am pissed and disgusted. I pay all my bills on time and this crap is the only thing negative on my credit report. im about to get married and buy a home. this needs to be removed
