Poor credit berue

It is with great sadness that i have to write this experian credit is one of the most badly credit beruae that i ever came to pass.I have spending more then R1000 rand in airtime just to hang on for more the 3hour hoping some one will answer.there is 4 frudelant accounts that im trying to despute for the pass year. All other credit berues data are accurate like xds transunion compuscan but just on experian there are 4 account namely montana general tradings196cc that i dont even know what they are selling. I must say costumer service if very poor experian if i had a choice i would prevere transunion as number 1 berue in sa they are quick to anser fone calls very helpfull experian on the other side the oppiste very upset and angry coz that accounts mess with my affodability and dropong my score
