Shocking service

I have been struggling for days to get hold of someone to answer the phone. The records that Experian holds are inaccurate and then when you want to dispute it you have to wait 20 business days for it to be updated. If transtrans union is updated then the companies are sending the paid up information to Experian as well but now I have to be inconvenienced by their apathy. Please get someone to contact me and I want my report rectified asap.
