EXPERIAN and BETTERBOND

i recently did enquiries at BETTERBOND and received a crdit bureau report from EXPERIAN. The info liked to my ID/profile were incorrect. I had relatives contact numbers listed as mine. Edgars account numbers belonging to other ppl loaded. periods of times listed that I was unemployed which were incorrect. Experian customer service consultant then forwarded a dispute form for me to complete BUT i need to provide proof of income and bank statements.....Im in shock...say what... to fix up the incorrect data?. Please do not use EXPERIAN if you require an accurate report. this is effecting my credit score.
