INCORRECT CREDIT REPORT

i requested my credit report but i was given my sisters credit report with my details and hers combined. i then requested for this to be corrected i was told it was correct, but they expected me to pay for the corrected credit report i do not think its fair because the 1st one was incorrect which basically means i have not receive my credit report.. i discussed this with one of the urgents but i was told i will get the report next year only. i did not make the mistake to combine my report with someones so i do not think its fair that i must pay for something they did not get right in the 1st place.
